If I enable ACPI on my box (Athlon XP at 1.6 GHz, Epox EP-8KHa+
mainboard), it becomes very slow (so slow that it's unusable).
Is this a known issue? Maybe the thermal limits are misconfigured,
and the CPU clock is throttled unnecessarily (if something like this
is supported at all).

I use the same board with ACPI enabled, no slow down.
The only problem I experience is that USB doesnt wakeup after resume from S3, reloading all of the related modules doesnt help, the port seems to be unpowered (usb optical mouse blinks for a few miliseconds after reloading uhci_hcd, maybe there is some little power left).

There have been reports before, check the archives. I seem to remember
that the solution involved changing some unobvious kernel feature, but
others have had similar problems.

Doing interesting things with little computers since 1979.
I had that problem with my old Athlon TBird. Changing config to make
thermal a module and not loading it solved my problem. I don't know how
to change the thermal limits from within the system using ACPI.

Could you post the output of "tail /proc/acpi/thermal_zone/THRM/*"?
Thanks.

This is at 57 C for me. 8-/
Probably that's why cooling measures kick in.
Yes because I turned on the box only a few minutes ago, now it is at 49 C.

Maybe it's related to the BIOS configuration. You can configure
limits there, and they seem to match those that are displayed under
/proc.
However, I still wonder if the 57 ?C figure is something I should
worry about (although the machine has been running stable for years).

This is clearly wrong.... But it is probably is not causing your
slowdown as 37 < 70.

Thanks for that. Good to know I can control the termal limits now.
