I'm running Debian 3.1 Sarge on a IBM Thinkpad R51. I use kernel
2.6.8-2-686.
When i shutdown my notebook it goes down, the screen went black, and all
LEDs are off. But the fan still runs and doesn't want to stop. I have
got to press the powerbutton for 3 seconds to stop it.
It's _a_ place to look, but sounds to me like he simply never completed
shutdown.
What filesystems are you running? I hope they're journalling systems like
reiser or ext3. Does it run the journals when you reboot? The first place
to look is at the last thing that showed in syslog.
