[Voyage-linux] Clocksource problem in 0.6 with alix 2c3

Hello guys,

It seems that something is still awry with mfgpt in 2.6.26. I have 
jiffies and tsc in 
/sys/devices/system/clocksource/clocksource0/available_clocksource - tsc 
is marked as unstable and the kernel defaults to jiffies. Shouldn't 
mfgpt be available, too? The obvious symptom of the problem is the 
severe clock drift I'm seeing.

 From dmesg

--snip
geode-mfgpt:  8 MFGPT timers available.
geode-mfgpt:  Registered timer 0
mfgpt-timer:  registering the MFGPT timer as a clock event.
--snip

then

--snip
Clocksource tsc unstable (delta = 193851888 ns)
--snip

and later

--snip
geode-mfgpt:  Registered timer 1
--snip

Any ideas?

I'm new to the Alix and to Voyage, btw. It seems ideal for my home 
gateway / file-serving needs... Good job!

Regards,

Nat
