[opensuse-kernel] VM swapping behaviour broken in 2.6.22.12-0.1-default?
by Lenz Grimmer 01 Dec '07

01 Dec '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I am desperately looking for clues on a very strange behaviour that I now have experienced with openSUSE 10.3 for several times now (actually, every 2-3 days on my Laptop, which is my primary workstation and up 24x7). The system works fine for 1-2 days, then all the sudden it becomes less and less responsive due to massive swap activity. Looking at the output of vmstat and free, I observe that the VM decided to swap out large amounts of memory pages, while there still was plenty of RAM freely available (not used for buffers or cache). So the system ends up with over half of the RAM being marked as free, while the swap has filled up quite significantly. This makes the system become *very* sluggish. It happened to me several times now that I returned to my desk in the morning and the system was completely unresponsive and the disk was rattling as mad. Only a hard reboot helped to regain control (Since I can't always wait ~1 hour for the Alt+SysRq+E to take effect). I filed a bug report about this a few days ago, it would be great if some kernel expert could investigate this and let me know, what other information I need to provide. https://bugzilla.novell.com/show_bug.cgi?id=340143 I toyed around with various swappiness values, but they don't seem to make a difference. Interestingly, even setting /proc/sys/vm/swappiness to "0" does not completely prohibit the system from swapping, while there still is plenty of free memory available: lenz@metis:~> uname -a Linux metis 2.6.22.12-0.1-default #1 SMP 2007/11/06 23:05:18 UTC i686 i686 i386 GNU/Linux lenz@metis:~> uptime 8:59pm up 10:54, 7 users, load average: 0.58, 0.61, 0.63 lenz@metis:~> cat /proc/sys/vm/swappiness 0 lenz@metis:~> free total used free shared buffers cached Mem: 1035332 1014084 21248 0 87160 197488 - -/+ buffers/cache: 729436 305896 Swap: 1253028 131076 1121952 lenz@metis:~> cat /proc/vmstat nr_free_pages 5250 nr_inactive 26913 nr_active 214996 nr_anon_pages 169683 nr_mapped 29874 nr_file_pages 79046 nr_dirty 721 nr_writeback 0 nr_slab_reclaimable 2394 nr_slab_unreclaimable 3436 nr_page_table_pages 965 nr_unstable 0 nr_bounce 0 nr_vmscan_write 135771 pgpgin 25483536 pgpgout 10607861 pswpin 14777 pswpout 36166 pgalloc_dma 169320 pgalloc_normal 29403345 pgalloc_high 2876515 pgfree 32454506 pgactivate 1380976 pgdeactivate 1156011 pgfault 35317571 pgmajfault 13960 pgrefill_dma 571625 pgrefill_normal 29974997 pgrefill_high 5063004 pgsteal_dma 91237 pgsteal_normal 7634076 pgsteal_high 333204 pgscan_kswapd_dma 191877 pgscan_kswapd_normal 7868615 pgscan_kswapd_high 430492 pgscan_direct_dma 3991 pgscan_direct_normal 289792 pgscan_direct_high 19388 pginodesteal 6 slabs_scanned 4068352 kswapd_steal 7819731 kswapd_inodesteal 17211 pageoutrun 132841 allocstall 3593 pgrotated 115105 Is there anything else you need?

[opensuse-kernel] problems with IDE driver reset after CD is ejected
by Gerhard Stengel 29 Nov '07

29 Nov '07

Hi, when I eject a CD after having copied some files from it I almost always get a reset of the IDE driver. I get following message in /var/log/messages: Nov 29 22:46:58 pfeil kernel: hdd: irq timeout: status=0xd0 { Busy } Nov 29 22:46:58 pfeil kernel: ide: failed opcode was: unknown Nov 29 22:46:58 pfeil kernel: hdd: DMA disabled Nov 29 22:46:58 pfeil kernel: hdd: ATAPI reset complete on my Suse 10.2 installation (running kernel 2.6.18.8-0.7-default on x86_64) I also installed Suse 10.3 on another partition in the hope it may be gone with the new kernel, but basically the same problem: ata2.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen ata2.01: cmd a0/00:00:00:00:20/00:00:00:00:00/b0 tag 0 cdb 0x1b data 0 res 40/00:03:00:00:20/00:00:00:00:00/b0 Emask 0x4 (timeout) ata2: soft resetting link ata2.00: configured for UDMA/33 ata2.01: configured for UDMA/33 ata2: EH complete This happens every time I push the eject key on the drive or try to use the eject command. Unfortunately, on the 10.2 installation the DMA is gone after the reset (even though I set keep_settings with hdparm - k 1 /dev/hdd, very strange!), on the 10.3 installation DMA survives, but the tray immediately closes again so that I have to very quick to snatch the CD out of the drive :-/ Both behaviours are not really optimal... The problem only occurs if I have copied some files from CD. If I just put it in and i.e. look a bit around in the CD's directory, there's no IDE reset. I have and AMD Athlon 64, mainboard Asus K8N with Nvidia Nforce 3 250 Chipset. The drives are a Lite-On DVD SHD-16P1S as IDE slave, master is a Benq DW1620. Had an AOpen DVD 1648 AAPro before, same problem. I thoroughly checked the cabling, Master/Slave are jumpered correctly. I even tried to put the DVD drives to separate IDE channels, but it didn't help. Any suggestion would be highly appreciated Cheers Gerhard -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] any way to get more debugging output from installation kernel?
by Toni Harbaugh-Blackford 28 Nov '07

28 Nov '07

Hi- I have been trying to install opensuse Factory to an Xserve G5, both via serial console and via 'usessh=1'. Both of theses methods hang early in the boot. The serial console install hangs just after the "rtas_flash: no firmware flash support" line: . . . smp_core99_probe smp_core99_kick_cpu smp_core99_kick_cpu done core99_setup_cpu 0 done SuSE Linux #1 SMP 2007/11/21 23:00:03 UTC [ 1.253833] rtas_flash: no firmware flash support The 'usessh=1' attempt hangs just after the "#1 SMP 2007..." line, so the "rtas_flash" line does not print. FYI, the last attempt was with kernel 2.6.24-rc2-git6-6-ppc64. Are there any other parameters I can pass to the kernel to figure out where this hang is occuring? I currently pass both debug and y2debug. Are there any other ways I can figure out what is going on here? FYI, I have installed factory to this system before without difficulty.

[opensuse-kernel] How to specify a flavor for a kernel build?
by Markus Elfring 18 Nov '07

18 Nov '07

Hello, I have got the impression that the description "WORKING WITH THE SUSE 2.6.x KERNEL SOURCES" in the document "README.SUSE" needs an update. http://forums.suselinuxsupport.de/index.php?showtopic=52969 I know how a specific output directory can be set. But this setting is independent from a flavor. Can it be specified without a change for the header "utsrelease.h"? Which is the current recommended way to configure it? Are there any command line parameters or environment variables which control the definition of macro symbols like "UTS_RELEASE"?

[opensuse-kernel] system reboots instead of shutting down
by Krupanský Rastislav 14 Nov '07

14 Nov '07

Hello I installed openSUSE 10.3 GM yesterday. I´m really disappointed, because bug 299882 isn´t still solved and the bug was probably reassigned to kernel. I can't shut down system. Still reboots. So, what can i do? Any advice? Thanks Regards, Rasto -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] Shutdown problems after Kernel update
by Christian Herr 14 Nov '07

14 Nov '07

Hallo ! Since I updated to kernel 2.6.22.12-0.1-default my laptop (Dell Inspiron 1501, Turion 64X2 TL50) has problems with the shutdown. When I log out of KDE and say turn off, everything is fine until the last step, where the computer normaly should power off. The last message that appears is something like "sending all processes the term signal...) and nothing more happens until I press the power button - this is when it really turns off. The same happens when I say "init 0" as root, "init 6" works fine. I am running OpenSUSE 10.3 with kde 3.5.7. The kernel update was from a official opensuse reopsitory, no build service. I updated last friday (november 7th). All other kernel updates that I got through the openSUSE repositories worked fine. Is there a switch or a config-file where I can configure what happens in the runlevels ? I would appreciate, if somebody could help me. Have a nice day, Chris -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] Check update process for "menu.lst"
by Markus Elfring 11 Nov '07

11 Nov '07

Hello, The YaST2 online update integrated the recent Linux kernel "2.6.22.12-0.1" in my system on Friday. I checked the file "/boot/grub/menu.lst" after this update. I noticed that there were two menu entries with the same title "XEN -- openSUSE 10.3 - 2.6.22.12-0.1". So I changed this to distinguish the PAE enabled one. The update process deleted the command "configfile" that I placed before the comment line "##YaST - activate" in my previous configuration.

[opensuse-kernel] Update to 2.6.22.12-0.1
by Markus Koßmann 08 Nov '07

08 Nov '07

HI all; I've installed more one kernel-source rpm installed on my system with rpm i --force : rpm -q kernel-source: kernel-source-2.6.22.9-0.4 kernel-source-2.6.23.1-20071018180544 kernel-source-2.6.23.1-20071018202431 kernel-source-2.6.23.1-20071019203748 kernel-source-2.6.23.1-20071025085103 kernel-source-2.6.23.1-20071026141715 kernel-source-2.6.23.1-20071029215823 kernel-source-2.6.23.1-20071102230003 kernel-source-2.6.24_rc2-23.1 When the update of the distribution kernel to 2.6.22.12-0.1came today, only the kernel-default rpm, but not the matching kernel-source rpm was installed by the updater. Is this expected behaviour or should I file a bug for that ? PS : In SUSE-10.2 all other kernel-source rpms were uninstalled when updating the distribution kernel(-source). That wasn't optimal. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org
