------- Comment #12 from [EMAIL PROTECTED] 2007-06-25 10:41 -------
I've been seeing this for quite a while on my Vaio SR17 (since Ubuntu Dapper,
which I think was 2.6.15 -- see https://bugs.launchpad.net/bugs/75174), but it
seemed to get a lot worse in 2.6.20 because it's apparently no longer possible
to kill kacpid or prevent it from running. Once kacpid gets going, the only
solution is to pull the power plug: the machine won't shut down normally.
I also see the problem with accessing the temperature file once the problem
starts. I tried this: in one window, run a big compile (gimp, kernel). In
another window, run top. In a third, run a loop that cats the thermal_zone file
every 5 seconds. If I don't run the thermal zone loop, then top will show
kacpid as the runaway process; if I do, then "cat" will be the runaway process
(kill -9 won't kill the cat), but either way the system becomes unusable after
a few minutes of compiling. The last temperature shown is typically about
71/72C (fairly typical for this machine during a compile).
