[Bug 372676] New: Regression: Suspend to disk freezes on HP 6715b after kernel update
https://bugzilla.novell.com/show_bug.cgi?id=372676 Summary: Regression: Suspend to disk freezes on HP 6715b after kernel update Product: openSUSE 10.3 Version: Final Platform: i586 OS/Version: openSUSE 10.3 Status: NEW Severity: Critical Priority: P5 - None Component: Kernel AssignedTo: pavel@novell.com ReportedBy: mhopf@novell.com QAContact: qa@suse.de CC: seife@novell.com Found By: --- On this HP Compaq 6715b laptop "powersave -U" freezes the machine, even when booted with vga=normal. This happens after an online update yesterday. I haven't had an update for quite a while. The last few lines on the display read: Looking for splash system... Mar 20 12:31:54 linux-ivhr kernel: swsusp: Basic memory bitmaps created splashy_start_splash: error -2none s2disk: Snapshotting system <blinking cursor> After trying to switch the VT, the cursor stops blinking, but nothing else happens. SysRQ still works. Kernel is 2.6.22.17-0.1, I also tried 2.6.22.5-31.0. This used to work on this machine, at least with kernel 2.6.22.12-SL103_BRANCH_20071114160351 (which I cannot test anymore, because the update nuked it from the disk !@#$). I also tried the kernel method with echo disk >/sys/power/state, same effect, there the last few lines state: Stopping tasks ... done Shrinking memory... done (0 pages freed) Freed 0 kbyte in 0.02 seconds (0.00 MB/s) Suspending console(s) <blinking cursor> Loaded modules are: Module Size Used by apparmor 40736 0 sha256 15232 0 aes_i586 37236 2 cbc 8448 1 blkcipher 10116 1 cbc usbhid 41300 0 hid 29184 1 usbhid ff_memless 9352 1 usbhid uhci_hcd 27024 0 dm_crypt 16904 1 loop 21636 0 dm_mod 56880 3 dm_crypt pcmcia 41076 0 firmware_class 13568 1 pcmcia yenta_socket 28684 1 rsrc_nonstatic 15872 1 yenta_socket ohci1394 36272 0 pcmcia_core 40852 3 pcmcia,yenta_socket,rsrc_nonstatic ieee1394 91136 1 ohci1394 battery 14724 0 parport_pc 40764 0 parport 37832 1 parport_pc container 9088 0 ac 9604 0 tg3 104068 0 button 12432 0 i2c_piix4 12556 0 ati_agp 12684 0 i2c_core 27520 1 i2c_piix4 k8temp 9600 0 hwmon 7300 1 k8temp rtc_cmos 12064 0 rtc_core 23048 1 rtc_cmos rtc_lib 7040 1 rtc_core agpgart 35764 1 ati_agp snd_hda_intel 272796 0 snd_pcm 82564 1 snd_hda_intel snd_timer 26756 1 snd_pcm snd 58164 3 snd_hda_intel,snd_pcm,snd_timer shpchp 35092 0 soundcore 11460 1 snd serio_raw 10756 0 pci_hotplug 33216 1 shpchp joydev 13632 0 snd_page_alloc 13960 2 snd_hda_intel,snd_pcm sr_mod 19492 0 cdrom 37020 1 sr_mod sg 37036 0 ehci_hcd 34956 0 sd_mod 31104 7 ohci_hcd 23684 0 usbcore 123372 5 usbhid,uhci_hcd,ehci_hcd,ohci_hcd edd 12996 0 ext3 131848 5 mbcache 12292 1 ext3 jbd 68148 1 ext3 fan 9220 0 pata_atiixp 12032 0 ahci 29188 6 libata 136776 2 pata_atiixp,ahci scsi_mod 140376 4 sr_mod,sg,sd_mod,libata thermal 19848 0 processor 40744 1 thermal I'm pretty much lost what else to try. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I also tried the kernel method with echo disk >/sys/power/state, same effect, there the last few lines state:
Stopping tasks ... done Shrinking memory... done (0 pages freed) Freed 0 kbyte in 0.02 seconds (0.00 MB/s) Suspending console(s) <blinking cursor>
..now _if_ we were able to dynamically disable the console suspend code, _then_ you would probably see where it hangs. People had already written code to do that, you know... ;-) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

You should be able to get the old kernel somewhere, no? At the very least, you could pull kernel cvs, and do bisect there.
I hope you mean git? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
