Do you still need a bisect, or is Andrews:
This Xen crash appears to be as a result of d1b6d0a0248 "x86: enable multi-vector MSI", and is likely a mishanding of some error state caused by the initial pci attach failure/partial setup.
enough ?
Thanks

Hi,
I'm trying to pass through a NIC (intel X520 with ixgbevf driver) to domU, but since kernel 3.8 this has not worked.
The dom0 kernel seems to cause the problem.
Xen version, domU kernel version and driver version seems to be unrelated to this bug, meaning
it works as long as dom0 kernel is 3.8.
I tried kernel version 3.9, 3.10 and 3.11 - all show the same bug pattern when used as dom0.
Can you do a git bisect on the kernel to find which kernel commit
triggers this crash?
This is clearly a Xen bug but it would be useful to know what triggered it.
Thanks.
David
