Red Hat Bugzilla – Bug 477506
segfault (error 4) in kernel message
Last modified: 2009-04-01 16:38:05 EDT
Description of problem:
Not really sure. The system got extremely sluggish for no reason I could figure out, and I barely got to drop to a tty to grab this dmesg dump. I've also been getting random whole-system total lock-ups where the mouse still moves but no keyboard input (C-M-Fn, Sleep, Hibernate, SysRq key combinations) that I've been trying to debug. I'm not sure if it's the same problem, and I got lucky grabbing this dump, or if it's unrelated.
Version-Release number of selected component (if applicable):
Not a clue, sorry. I'll try to get a stack trace and/or figure out what triggers it soon.
Steps to Reproduce:
System nearly locks up and I get the following kernel messages.
System keeps running as normal.

assigning -> glib2
no idea why you think a kernel BUG would be a glib2 issue...
Could you confirm the issue with the latest kernel in F10 updates ?
Additionally, could you add full dmesg and /var/log/Xorg.0.log as uncompressed text attachments as well ?
The information we've requested above is required in order to review this problem report further and diagnose or fix the issue if it is still present. Since it has been thirty days or more since we first requested additional information, we're assuming the problem is either no longer present in the current Fedora release, or that there is no longer any interest in tracking the problem.
Setting status to "CLOSED: INSUFFICIENT_DATA". If you still experience this problem after updating to our latest Fedora release and can provide the information previously requested, please feel free to reopen the bug report.
Thank you in advance.
