"clock timer configuration lost" error?

[Tim Moore]

For no apparent reason:

Anyone have a clue about the 'probable hdw bug' messages?  No disk
activity to speak of, no other symptoms and/or messages.

Small number of VIA 686 boxes randomly jump from 100Hz back to the DOS 18Hz
timeout. We dont know if its hardware or maybe APM bios bugs. The kernel puts
the timer back and life appears happy again

Interesting.  This is a KA7 with all power management turned off in the
latest Abit BIOS.

Ahhh.  The kernel *is* god.

Well, I have a pentium 66 (o/c @ 100) with a probably very old HP bios,
and I have the problem... and I don't think my Computer have a
VIA686a...
Fun...
