Description Chris Lalancette 2009-04-08 14:14:45 UTC
Description of problem:
Recently a patch was put into the upstream linux-2.6.18-xen.hg kernel:

http://lists.xensource.com/archives/html/xen-devel/2009-03/msg01179.html

Essentially, it makes sure that we don't discard the NTP sync when we update the Xen wallclock from dom0.  It looks like we'll probably need this in RHEL-5, although I'm not entirely sure yet how to prove it's working or not.  It was committed to upstream linux-2.6.18-xen.hg as c/s 832.

Comment 1 Rik van Riel 2009-04-08 16:07:16 UTC
Yes, we want this changeset.  It could even help fix some of our long-standing PV timer bugs...
