Red Hat Bugzilla – Bug 236275
kernel: BUG: soft lockup detected on CPU#0!
Last modified: 2014-03-16 23:06:14 EDT
Description of problem:
SSIA. No traceback. :/
Started with 1.3045.fc7 or so. No real rhyme or reason. Happens
when opening windows in X, or switching desktops, or sitting idle.
(Note: not using DRI/compiz.)
Version-Release number of selected component (if applicable):
*hand waving happens here*
Not really much to do without a traceback.
Though given softlockups stellar track record, I'm tempted to increase the
amount of time it waits before it cries wolf.
hmm, then again, it's at 10*HZ right now, which should be ridiculously high already.
What X driver is this? Any chance of serial console or netconsole capture?
FWIW, most of the time it just hardlocks - only got the 'BUG' message once.
No serial port, will try !wireless to see if I can get a netdump. radeon driver.
Closing. This box has steadily locked up more and more often, and now
occasionally dies beeping in the BIOS.
