Symptoms: Interactive work suddenly hangs. Frequently that is when doing some graphics operation like opening or closing windows, but also often with typing the second character of the password in the kdm login screen. The KDE panel clock increments the seconds for some time afterwards, sometimes for around 60s. Switching to a text console and attempting to log in always hangs. Remote login over Ethernet is never possible. There is no longer any ping response either, though I have only tested that after about a minute. There is no output by dmesg that I could find. When it became clear that the disk is non-responsive in these hangs, I set up remote syslog logging over RS232C, and later over Ethernet. The syslog content related to this problem is absolutely zero, there are only the usual entries from cron, smartd, etc. Setting the console log level to 9 during boot increases the fluff a bit, but still shows nothing out of the ordinary. This problem exists since May 2011 with openSUSE 11.4. Hardware details: 1) Phenom II 1090T, Gigbyte GA-880GA-UD3H mobo, chipset AMD 880G, AMD SB850 00:00.0 Host bridge: Advanced Micro Devices [AMD] RS880 Host Bridge 00:02.0 PCI bridge: Advanced Micro Devices [AMD] RS780 PCI to PCI bridge (ext gfx port 0) 00:09.0 PCI bridge: Advanced Micro Devices [AMD] RS780/RS880 PCI to PCI bridge (PCIE port 4) 00:11.0 SATA controller: ATI Technologies Inc SB700/SB800 SATA Controller [AHCI mode] (rev 40) Two disks, both connected via SATA 6G, not 3G. nvidia Geforce GT220 openSUSE 11.4 The filesystem on / is reiserfs, there is no /boot partition, booting is from / and MBR. New installation. System new in May 2011, problem exists since then. I was never sure whether it's a hardware or software problem, and having nothing too concrete, didn't file a report. I verified that the problem also exists with the nouveau driver and wthout the nvidia driver being loaded. 2) hp compaq dc9100 00:00.0 Host bridge: Intel Corporation 82915G/P/GV/GL/PL/910GL Memory Controller Hub (rev 04) 00:01.0 PCI bridge: Intel Corporation 82915G/P/GV/GL/PL/910GL PCI Express Root Port (rev 04) 00:1c.0 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Express Port 1 (rev 03) 00:1d.0 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) USB UHCI #1 (rev 03) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev d3) 00:1f.1 IDE interface: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) IDE Controller (rev 03) 00:1f.2 IDE interface: Intel Corporation 82801FB/FW (ICH6/ICH6W) SATA Controller (rev 03) The disk is SATA connected. openSUSE 12.1 reiserfs on / , (it was like that with oS 11.1 too), re-formatted for installation, no /boot partition, booting from / . New installation. This exact same box has been rock-solid for years with openSUSE 11.1, so it's not a hardware problem. Hangs started before the initial installation was completely finished. Afterwards several hangs per day, sometimes before login was completed. KDE system. nvidia 7300 of sorts, problem started before the nvidia driver was even installed. Seeing the same problem again I had two systems to compare. Looking for similarities left reiserfs and KDE. I don't see how KDE can cause what looks like a kernel problem. After a week it became clear that this was unusable, and I replaced the root filesystem (reiserfs) with ext4. Lockups in the following 10 days: zero. Up to oS 11.1 reiserfs was very solid for 10 years. Since 11.4 it is actively dangerous. I never lost data, but the loss of time with box 1) was very significant. The problem is not caused by the nvidia graphics driver. Reproducible: Sometimes Steps to Reproduce: Can't give an exact recipe for reproduction. Install oS 12.1 on a x86 (32 or 64bit seems to not matter), with reiserfs as root filesystem, and use the system for a day with a lot of graphics operations. Expected Results: This is Linux. Kernel and crash are mutually exclusive :-) -- 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.
