With sles11 dom0+domU there are no more hpet1 messages when started from
xend.


With xl however I now get a hanging guest, which I did not see before this
patch. But this happens only if it is booted with quiet, with 'debug
ignore_loglevel' booting works fine.
Also xl list shows the domain in paused state?!

I will try once more with sles11 kernel, xl and the RTC patch reverted..

xl dump-core shows just this in dmesg:
