Greg, I apologize as I've forgot to cc the mailing list. Anyway some people in the VFIO Discord were having similar issues and reverting the commit below fixed their issue. https://github.com/torvalds/linux/commit/052f71e25a7ecd80a9567b291df8ea333d9a8565 I just tested and it has resolved my issue as well. It would seem as though that patch is the offender. Also below I have the kernel oops in a pastebin for you. https://pastebin.com/D51uZCFU Thanks!
