Re: debian lenny installation on an ibook g4 keeps freezing

I had an iBook with a not-working-right fan, and I found last summer that I could prevent thermal shutdown by putting dead hard drives in the freezer, and resting the iBook on them one at a time. I had five in rotation for about a month until I felt confident enough to take the beast apart and fix the fan.

During the install, switching to another console and running

# modprobe therm_adt746x

should let you access the thermal monitors with

# cat /sys/devices/temperatures/sensor*_temperature
