Hi y'all,
Last week this Puny Pentium2 measured correctly at
around 448MHz. Today's kernel+modules show it as
about 202MHz. Snipped from today's dmesg:
[...]

I know -Current is currently messin' with the timers.
But this ain't near right as it stands with the latest
CTM deltas. ;) It is causing premature timeouts when
waiting for some background tasks before bringing up the
ttyv's. The snip below only shows on the console (not in
dmesg or messages etc.):
[...]

Not sure if this is going to affect other timers (main
use is for development; I don't run much other stuff).
(BTW we _hafta_ use APM; the latest ACPI changes haven't
fixed IBM Crystal Sound[tm] yet; I'll do-up another post
on that if needed, already sent bios dumps to acpi-jp@
quite some weeks ago.)
Anything I can do to help...
-- thx, Paul Seniura.
