[gentoo-user] Weird lockup problem

[Roy Wright]

Howdy,

I've been having a weird problem for the past month where about twice a
week when I first unlock the system in the morning, the mouse moves
really slow (about 1 second update rate) and if I press any key except
ctl-alt-delete (which reboots the box but does not display the shutdown
messages to the console), the mouse pointer goes away and the system is
totally unresponsive.  Also can't connect (ssh, ping, nfs) to the box
when this happens.  So far I haven't found any log messages even hinting
at the problem.

This system is a ~x86 and after 3 years of running a gentoo workstation,
I'm at a loss on how to trouble shoot it.

Thank you,
Roy

I have sometimes left a job running like this

    while :; do
	top | head >>/tmp/busylog
	sleep 30
    done


It's awful but it sometimes provides clues.  The important trick is to
append to the log inside the loop rather than after the done, to force
the buffer flush each time.
