Dothan CPUs and speedstep
ipw2100 and C3
On some Thinkpads there is a problem with the ipw2100 wireless LAN driver when C3 is enabled. It results in frequent firmware restarts due to data corruption. If you see this problem frequently and want to disable C3 but still use C2 and the thermal management, you can apply this patch to the file /usr/src/linux/drivers/acpi/processor.c
APPLY THIS PATCH ONLY IF YOUR SYSLOG REPORTS DRIVER RESTARTS AND FIRMWARE RELOADS ALL THE TIME! This patch causes slightly shorter battery life.
