Public bug reported:
It happened a few times now, when there's a process that requires high CPU
usage after about a minute the system freezes completely. I see activity on hdd
and hear the cpu working at full load, but the system does not respond to any
command. The mouse freezes and if I try to move it I can only see some little
movements after a while. No response to commands keyboard shortcuts to restart
X server or to change to other consoles or Alt-Sys magic combinations.
It seems to only happen when both CPUs are at full load. (I think there is a
priority on processes so the system doesn't freeze)
It happened the first time during a compiling, some time after giving the
command "make".
Then it happened again during a bad command (too much high parameter in "change
tempo" dialog) in Audacity.
Now it happened again loading a virtual Linux machine in VirtualBox, just after
(virtual) login. Well, this time I was also playing music in Amarok, and
downloading a torrent from Transmission! ;) But I always have at least these
two applications running along a virtual machine, and other times it didn't
froze!
Anyway, these are my specs:
