Having just said, that xen-unstable is lost (including logs): I would
test whatever you want me to test, I am a bit lost between all these 
things in conjunction with power and idle management. It's quite 

Just tell me what exactly you want me to do...

Interesting.  This is reported booting dom0, correct?  Are
you running NTP in dom0?

Tim, do you suppose this is an extreme example of the NTP
interaction bug you fixed here:

No, it is good to raise awareness of these issues until they
are all fixed.  ESPECIALLY if you see time problems in xen-unstable,
it would be good to get them fixed before 3.4 is final.

Just an observation, to whom it may concern: when booting between 3.3.1 
current xen-3.4-unstable, right after loading powernow-k8, there will be 
one huge
Time went backwards messages (500ms upt to 1,5s), which disappears 
you change Xen version again.

BTW: If I get on your nerves with my time keeping issues, just drop a 
note and 
I keep calm ;-).
