Hi,
I have a problem with too fast clock in dom0.
The clock is 3-4times faster than 'real' clock.
In users list I got an advice suggesting that it is a hw bug. But I have
no other problem with the hw and
I hope it is a xen bug (or my misconfiguration) and it can be fixed or
workarounded.
It happens on a notebook compaq evo N115 (Duron 996MHz).
On my desktop with similar configuration there is no problem (xm dmesg
attached for both).
I tried to locate the bug myself but with no luck :( Could you please
suggest some hints where
to start debugging?
