Subject: [hv] BUG: kernel freezes after [   13.356381] PCI: CLS 0 bytes,
 default 64

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 <kys@...rosoft.com>

    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).
