brutal shutdown

[Yves-Alexis Perez <corsac@corsac.net>]

Hi there,

since some days (don't know exactly when, but some days ago, and it
keeps increasing), my powerbook (g4/15" 5,6) stops suddenly. Brutal
shutdown without anything written in the logs.

Firs times were while it was idle, during the night for example, but
tonight it shutdown itself like 3 times, and once while I was in front
of it, typing on the keyboard.

I've checked the temperature:
corsac@hidalgo: cat /sys/devices/temperatures/sensor2_temperature
49
corsac@hidalgo: cat /sys/devices/temperatures/sensor1_temperature
50

I don't think it's that high, and if it was really a temperature problem
i'd say it should have been written in the logs. Maybe there is hardware
failure involved, but I don't really know.

Has someone got the same problem recently, and could this be a soft I'm
running (using Debian Sid, running pmud and pommed).

Regards,
