It should be further noted that these changes introduced a regression
into Win2003 SP3, resulting in intermittent guest hangs on boot.   That
regression is the next item on my Xen 4.3 regressions list, after
getting the HPET host crash fixed.

Also (I am not really sure which category this resides in)

* HPET interrupt stack overflow (when using hpet_broadcast mode and MSI
capable HPETs)
  status: patches posted, undergoing review iteration.
