Just last week I was running staging to test pvscsi on this HP ProBook 6555b, since around Wednesday I think. But todays staging fails to boot. So I started a bisect in xen/, but every attempt to boot xen.gz results in a hang at the same place. Even going back to the state of 4.5.0. Any idea what may cause this hang, and how I can debug it further? Without sync_console it barely gets past "SVM: Supported advanced features:", on VGA it always gets to the "PVH mode not supported" line.
