[opensuse] kernel panics with v13.1 (+?)
I installed opensuse v13.1 in December on my home desktop. Generally OK, but with some glitches (e.g., sound but no volume control). My persistent problem is that (after being away for several hours or a day or two) the system can freeze. The CapsLock and ScrollLock lights are blinking together, but everything else is dead. It can even not be reached via ssh (hence I can not see any current messages). A couple of times I found diagnostic text on the screen. Having already tried unsuccessfully to find such text in system log files, I copied some of the text by hand: [OK] Reached Target Multi-User System [OK] Reached Target Graphical Interface [time] Kernel panic - not synching: Watchdog detected hard LOCKUP on cpu 0 <Note, has also been cpu 3> [time] CPUID PID 690 Comm: systemd-logid Not Tainted 3.11.6-4-desktop #1 [time] Hardware Name Acer/Aspire M3450/Bios P01-A2 09/30/2011 <3 lines of hex> [time] Call trace: <21 lines> [time] drm-kms-helper: panic occurred, switching back to text console Although it has worked fine on v12.3, I suspected the radeon HD 4250 driver. After a comment on this list, I added radeon.dpm to the boot menu. I keep the rpms up to date. It seemed to be doing better recently (until today). BUT: a couple of days ago I tried to ssh into my computer at work. It could not be reached, although other computers in my group were OK. When I got to my office, I saw the 2 lights flashing, and the system was dead. But this computer is still at v12.3 ! It has a dual-core Athlon II X2 255 processor (instead of the FX-4100 at home), and also a GT200 GeForce 210 video card with the nouveau driver. It had been working fine. Has a bug crept back into the kernel (as suggested by some of the web discussions) and is getting backported? Is it some problem with systemd? I see some hints in the /var/messages file, but not definitive. What is needed to fix the problem? Thank you.

After being away for just a couple of hours, I found the system frozen with the screen display just as I had left it. I will have to go back to v12.3 to test that I do not get this problem.

Replying to my own post, because I hit send too soon... If this can be repeated, you may find something in the log which will be of interest. In the past, I've actually tailed the log via ssh from another machine to make sure I get these messages. Its almost always been ultimately tracked down to bad memory or bad disk drive in the few times I've had such issues in the past. I think it can happen if you completely fill your disk as well. But It's been several years since I had a panic. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
