Description Bill Nottingham 2007-04-12 16:02:03 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.
Comment 2 Dave Jones 2007-04-13 15:09:16 EDT
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?
Comment 3 Bill Nottingham 2007-04-13 15:12:48 EDT
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.
