Description Kostas Georgiou 2006-08-19 17:42:19 UTC 
The PMTimer doesn't get detected in an Asus A8V Deluxe motherboard (VIA
K8T800Pro) so the system uses TSC (even when you use
the notsc kernel option). This results in problems (#174390 for example) with
dual core cpus since TSC isn't stable there.
$ dmesg
...
time.c: Using 1.193182 MHz PIT timer.
time.c: Using PIT/TSC based timekeeping.
...

Under FC5 the PMTimer is detected fine in the same motherboard (with a single
core cpu though)
$ dmesg
...
ACPI: PM-Timer IO Port: 0x808
time.c: Using 3.579545 MHz WALL PM GTOD PIT/TSC timer.

For some reason bugzilla doesn't allow me to close it as duplicate.
"You tried to change the Status field from NEW to CLOSED, but only the owner or
