[opensuse-factory] untraceable instability with Kernel:/HEAD
i've been using Kernel:/HEAD, X11:/XOrg, and the latest nvidia driver for a long time on openSUSE 11.4 (x86_64) with KDE 4.6 (KDE:/Distro:Factory) without any real problems. since 10 days or so my system freezes now & then with no recognizable pattern, leaving no traces in Xorg.0.log, messages, or anywhere else as far as i can see. downgrading one or two kernel versions and to older nvidia drivers, even 256.53, didn't change anything; yesterday i downgraded to the oldest kernel i still have, 2.6.37-41-desktop, and so far everything runs stable. this doesn't really bother me, since for my use there isn't any noticeable performance hit with the older kernel, but i'd like to find out what's going wrong. is that what Kernel-trace is for? if yes, how would i go about to trace these crashes? -- phani. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

The easiest ways are to set up a serial console (preferred) or to set up kdump to capture the oops. kernel-trace is about performance tracing, not debugging. -Jeff -- Jeff Mahoney-- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

thank you, that clarified things for me. i've installed kdump & co, but before i got around to set it up and wait for another crash, Kernel:/HEAD came out with RC4 of kernel 2.6.38, and my system is stable again. no point debugging an outdated release candidate; but good to know the process for the future. -- phani. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
