Hi, not easy to choose the right mailing list.
On factory 12.1 RC1+ I'm normally build my local package with osc build --local-package I use kvm + one lvm for the root, and one for the swap.
This config has worked months.
After the last 3.1.rc9-1.2 upgrade I get really strange crash which I can't debug or understand So if one of you can give me some pointers to open and report correctly the bug. I've already reformated lvm, rebuild initrd etc ... (basics stuff)
With your help I will be able to drive that bug against kernel, kvm/qemu + kernel, or osc. Thanks ... Google, Inc. Serial Graphics Adapter 10/21/11 SGABIOS $Id: sgabios.S 8 2010-04-22 00:03:40Z nlaredo $ (abuild@build25) Fri Oct 21 14:37:36 UTC 2011 4 0 SeaBIOS (version 1.6.3-20111021_143732)

Given it died in the idle task and interrupts are disabled, an interrupt came. But the (low-level) handler for that interrupt vector is NULL. So this is a bug in the irq setup code. regards, -- js suse labs -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
