Description of problem: The arts soundserver crashes at the beginning of the KDE session. The moment I click OK to close the window informing the crash, the system freezes (I think it's a kernel oops) and it stops responding even to keyboard commands, I am forced to shut it down using the power off button of the computer. Version-Release number of selected component (if applicable): kernel-2.6.23.9-85.fc8 How reproducible: Always Steps to Reproduce: 1.Start KDE session 2. 3. Actual results: System freeze Expected results: Working KDE session Additional info:
Created attachment 292258 [details] Soundserver crash window
Created attachment 292259 [details] Soundserver backtrace
Created attachment 292260 [details] kernel OOPS trace If I leave the soundserver crash window alone, I can use the system just fine. As soon as I try to close it or look at the backtrace, the kernel freezes.
Same as bug 391971, except mine triggers a kernel OOPS.

(In reply to comment #4) > Same as bug 391971, except mine triggers a kernel OOPS. Can you confirm this is a single-processor system?
If you boot with the kernel option "noreplace-smp" does it prevent the kernel OOPS when this happens?
My computer is a single-processor system (2 GHz Intel Pentium M).

Patch went in kernel 2.6.23.14-118.
> And can you confirm this happened on a single-processor machine? Yes, AMD Sempron 3000+ with Cool 'n' Quiet activated on Asrock mainboard.
I think I know what may have caused the bug on my system: I'm using a webcam for which the driver is not yet included in the kernel modules. I need the OmniVision 519 driver and I compiled the version provided on www.rastageeks.org Not having the webcam connected at startup solves the soundserver problem and therefore the kernel oops... Hope this helps
