[Bug 17589] Re: System clock runs far too fast

[Martin Kalén]

FYI p2k and others: on Shuttle motherboards the system clock frequency
can suffer badly from CPU over-clocking. This is not specific to any
operating system and was verified with a Shuttle SN45 under Ubuntu,
Slackware and Windows XP. With CPU frequency settings set to
"Aggressive" in BIOS, my clock was running way too fast (everything from
a few seconds to fast per 1-10 minutes up to double speed with two
second ticks per wall-clock second). Settings CPU speed to "Optimal" in
BIOS solved the problem for me.

(CPU: AMD Sempron 2800+. Additional BIOS settings: ACPI=ON, MPS-
level=1.4, Memory timings=Aggressive, C1 disconnect=AUTO.)
