--- Comment #9 from Jeff Cook (jeff@jeffcook.io) ---
I've been getting a very similar crash on 4.12.x, also making heavy use of PCI
passthrough. Came across this bug, as I've been searching regularly looking for
others encountering the same troubles.
A snippet of the log observed on 4.12.{3/5}:
kernel: BUG: unable to handle kernel paging request at ffffffffc0955f96
kernel: IP: report_bug+0x94/0x120
kernel: PGD a67a0c067
kernel: P4D a67a0c067
kernel: PUD a67a0e067
kernel: PMD 495886067
kernel: PTE 800000049bbdd161
Last night I experienced a hard lock with 4.11.9, which has heretofore been
stable. The system did not log any information about that crash. This may mean
that the issue existed prior to 4.12, but was just much harder to trigger.
