I've compiled kernel 2.4.20 with the ACPI patch on my Fujitsu Lifebook.
Now I get most of the devices in the /proc/acpi directory. Except
/proc/fan and /proc/thermal_zone directories are empty.
Under what conditions does this happen? I've been reading the code in
thermal.c, but so far I haven't been able to figure this out.
Any hints would be greatly appreciated.
