Good people,
I was looking at thermal states switching by acpi_thermal.c and it looks
like follows (provided that temperature raises and falls slowly and
gradually):
NONE =up> AC2 =up> AC1 =up> AC0 =down> NONE (1)
I do not know whether this was intentional or not and, for me, something
along the lines of
NONE =up> AC2 =up> AC1 =up> AC0 =down> AC1 =down> AC2 =down> NONE (2)
seemed more natural.
If (2) and not (1) was indeed the desired behavior attached patch seems
to do the job. If (1) is what was intended, I do apologize for the
noise.
I am running -CURRENT from February 3.
