Over the last month or so I have been seeing a kernel traps that leave the system unstable; a reboot is necessary. This is since I have upgraded to kernel 2.6.34.7-0.7-desktop x86_64.
Many of them are due to broken fglrx. Could you retry without that module? -- 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.

Many of them are due to broken fglrx.
Those failures only occur at startup. I forgot to mention in the previous comment (#2) that the uploaded "messages" file is where to look for the kernel traps. Note: Due to Thunderbird's habit of aperiodically resetting my preferences, I missed the timely arrival of this request. -- 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.

The logs are still tainted by fglrx. Can you reproduce it without that module? The module is not needed for X to run. just for 3D. If yes, it seems like somebody holds a i_block_reservation_lock. Could you grab dmesg after: echo t >/proc/sysrq-trigger. -- 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.

rpm -i kernel-debug-devel-2.6.34.9-201105102339.x86_64.rpm error: Failed dependencies: kernel-devel = 2.6.34.9-201105102339 is needed by kernel-debug-devel-2.6.34.9-201105102339.x86_64
which I find confusing since:

Where do I find kernel-debug-2.6.34.9-201105102339? (I found lots of distributions for fc13.)
Do you need the devel package at all? I don't think so, so just ignore it and install only kernel-debug-2* (you don't even need the -base package). -- 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.

Yes, since the VBox kernel build requires it. The kernel-debug-2* and kernel-kernel-debug-base-2* are insufficient, and kernel-debug-devel-2* requires kernel-devel-2*. -- 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.

Hmm, wasn't there anything even in the VGA console?
I do not know what you mean here.
Also what does mean frozen?
AFAICT, non-functional. No response to the keyboard, capslock or numlock had no effect; no mouse pointer movement; no video updates, the screen was completely static. I did not try to ping it from another computer. -- 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 do not know what you mean here. I suppose you are running system with X right? So if you press ctrl-alt-f10, you will be put to a text console with syslog. If kernel spits out something just before it dies, it's likely to be visible in this console. So it would be good if you can start your reproduction load and then switch to this console to see what kernel writes before it dies.
Also what does mean frozen?
AFAICT, non-functional. No response to the keyboard, capslock or numlock had no effect; no mouse pointer movement; no video updates, the screen was completely static. I did not try to ping it from another computer. OK, so the kernel probably died with interrupts disabled. Good to know.
