The laptop is running idle, just running xfce4, some applets, and some desktop
applications (thunderbird, firefox, pidgin). If I run boinc (einstein/seti/simap)
from the ports on a few days old kernel, the temperature rises to 87C-92C, against
67C-72C when idle. At some point the cpus get too hot I guess, judging from a
frozen console (the video card is still pushing out the screen image) and a hung
ssh connection. Then only power cycling helps.
kernel config and loader.conf are attached.

Rene
