ACPI problem in Kernel 2.6.20

ACPI problem in Kernel 2.6.20

[Paulo J. Matos]

Hello all,

I've been installing gentoo on a HP Compaq tc4200 tablet PC and things
seem to work fine except ACPI which (through kacpid) eats up my
processor constantly by 100%. This is definitely a problem since
passing noacpi to the kernel (although it solves the kacpid cpu
hunger) removes the possibility of havin battery, fan, cpu temp, etc.

Any ideas on how to solve something like this?

Cheers,

Paulo Matos

Sorry for having posted in private, I should have done a "reply all"...
I think we should come back into the list so that it may help other
people and other people may help... ;-)

If I well understood, this is a (often bugged due to a M$ compiler...)
table the OS uses to know how to deal with ACPI. I guess that newer BIOS
versions than yours might have a corrected ACPI table, but I'm afraid I
can't help you further...

Well, thank you. Right now I'll try to compile 2.6.21 and then see what happens.

Unfortunately 2.6.21 doesn't work either. Maybe I should update the BIOS...
