Greetings, I got the below dmesg (kernel freezes at the end of it) and the first bad commit is commit cf6a2eacbcb2593b5b91d0817915c4f0464bb534 Author: K. Y. Srinivasan Date: Thu Dec 1 09:59:34 2011 -0800 drivers: hv: Don't OOPS when you cannot init vmbus The hv vmbus driver was causing an OOPS since it was trying to register drivers on top of the bus even if initialization of the bus has failed for some reason (such as the odd chance someone would run a hv enabled kernel in a non-hv environment).
