I like to add a possible culprit to the mix, that could also explain
the overheating. From time to time my TPad R60 gets really hot and I begun
using a utility (cpuspeed 1.4) to throttle down my CPU. Judging from the
output of this utility I see that my CPU after some time is running at
100% and the program is not able to trottle the CPU down anymore, heavy
IRQ load.

I tested different versions of ACPI this weekend, with version 3.13
my WIFI led was flashing a lot and I also lost my connection. With
version 3.11 my WIFI led isn't flashing, but from time to time I still
have my CPU at 100%.

What version of ACPI are you using? (bldlevel \os2\dll\acpi32.dll will
tell you the version).

Kind regards,
