My workstation is freezing up a lot again (usually in 30-60ish second
bursts with no or very slow response to mouse or keyboard or screen
updates).
I have a status bar (xstatbar) that displays a graph of the last minute
or so's cpu% split off into user/nice/system/spin/interrupt/idle. It
skips a lot of updates when the machine freezes but it's obvious that
it's mostly in spin.
It seems particularly likely to occur when opening browser tabs.
Is there anything sane that I can do (ahead of time, as I can't type
when it's in that state) that will give clues about what's going on?
dmesg below, FWIW.
