I've run into a very odd problem on a IBM Netvista 8307 (which has an
Inetl 845G motherboard). As soon as the kernel loads the CPU and case
fan stop spinning. Neither will reactivate even when the system is put
under load. Doing this just causes the machine thermal alarm to go off
and basically shutdown.
Booting up using APM instead of ACPI and the fans appear to operate
as expected. Currently I have the 2.6.7 kernel with Debian patches
Thanks in advance.
