Squeeze lockups
Several times lately I have come back to my computer to find it locked up so
tight I have has to do the alt-sysreq thing.
One one or two occasions Firefox (3.5.3) was left running...other times nothing
was running.
I run Fluxbox on a dual core Pentium with a gig of memory.
This is part of syslog:

This whole sequence is repeated 8 or 10 times in the log.
The lockups only started a few days ago so it may have something to do with an upgrade.
None of the log makes any sense to me :) Does it make any sense to anybody ? Any ideas what's causing
the lockups?
