Hi Mark,
that either the acpi bios is buggy/broken (can't make any useful sense to
explain the problem) or the standardize ACPI thermal infrastructure(and it's
linux OSPM counterparts driver fan.ko/thermal.ko) is not the one that really do
the job to regulate your fan under linux.
Grepping the kernel source code I found toshiba has it own platform driver that
provides means through procfs to control the fan, and userspace acpitool seems
to be able to leverage it to control it. If so then the focus of this problem
should put from thermal zone to this platform driver and any userspace tools
that defines the fan policy ?
See if you have this toshiba plaform driver (toshiba_acpi.ko) loaded and
procfs?
1. lsmod | grep toshiba_acpi
2. ls -la /proc/acpi/toshiba/
Thanks.
