RE: [Xen-devel] Re: BSOD "A clock interrupt was not recevied onasecondary processor within the allocated time interval"
This is very similar to the patch we have on top of the original Novell stuff.
Steve Ofsthun was digging through the new viridian.c code at the end of the day yesterday to see if this bit was set. This fix below should do the same thing.

Hmm... In order for the Viridian stuff to actually solve this
problem, you need to set the relaxed-timers bit. It doesn't look like
the xen-unstable implementation does so. Something like this might
help:

}
But note that I haven't tested this *at all*.
