I just discovered a few page allocation errors in dmesg on dom0.  xm dmesg attached.  It's not a full crash, dom0/domU are still up.  Any ideas for things to check or additional information to provide?


Ubuntu Lucid alternate install
Xen 4.0 testing (last commit Oct. 18th 21368:5221fcc3df64)
dom0 2.6.34 (base release) + Andrew Lyon's patches
