No, i have no idea, it really sounds like a kernel problem.
There are workarounds for fan problems in pm-utils, but i'm not sure if they
are already upstream or only in our package. They look like:
-----
#!/bin/bash
kick-fan()
{
local FAN DUMMY STATE
for FAN in /proc/acpi/fan/*/state; do
[ ! -e $FAN ] && continue
read DUMMY STATE < $FAN
if [ "$STATE" = "on" ]; then
echo "kicking $FAN"
echo -n 3 > $FAN
echo -n 0 > $FAN
fi
done
}
case $1 in
thaw|resume)
kick-fan
;;
esac
------
But even if this helps, it is still a kernel problem and should be
reported on acpi-devel.
