[opensuse-virtual] reproducible panic @ 'new' 2.6.34-1-xen domU boot on pvgrub host
with the migration of Kernel:/HEAD repos to 2.6.35x branch, i'm testing a dropback of DomU boot from 2.6.34-49.1-xen @ .../Kernel:/HEAD/openSUSE_11.2 to the 'new' repo @ .../Kernel:/openSUSE-11.3/openSUSE_11.2, w/ 2.6.31-1-xen. atm, (1) boot on an OpenSuse 11.2 Dom0 host (atm, still 2.6.34-49.1-xen) with either 2.6.34-49.1-xen or 2.6.31-1-xen DomU seems OK. (2) boot on a PV-GRUB host (@ Linode), which had been working fine w/ DomU earlier 2.6.34-X-xen, X ~< 35 (? iirc?) was, previously, OK.
