Every 20 or S3 suspends, the machine shuts completely off: It goes to sleep
fine, the crescent-moon LED turns on, I put it in my backpack to go home, and
then a few hours later when I open the lid to wake it up, nothing happens.
Whereupon I notice that the crescent-moon LED was not on anymore, and the
machine needs to be rebooted.
My first theory was that the battery ran out. But that was never the case.
Most always the battery (checked after rebooting) is around 90% or 95%.
I don't know how, but maybe it oopsed a while after going to sleep? There's
nothing in the log files, of course, so it's been hard to debug.
The hardware is a Thinkpad T60 with Intel graphics, wireless (untainted
kernel). The machine runs Debian unstable but with the vanilla 2.6.29 kernel.
I had noticed this problem with vanilla 2.6.27.4, and upgraded to 2.6.29 in the
hope that it would go away. But if anything it has become more frequent.
