KVM guest freeze on Linux > 4.19

KVM guest freeze on Linux > 4.19

[Garry Filakhtov]

Good time of the day,

Hope you all are staying safe during these challenging times.

I have been struggling with KVM guest freezes after the upgrade from
4.19 LTS to 5.4 LTS.

Searching through the internet lead me to
https://www.reddit.com/r/VFIO/comments/b1xx0g/windows_10_qemukvm_freezes_after_50x_kernel_update/
and Kernel Bugzilla revealed
https://bugzilla.kernel.org/show_bug.cgi?id=200101. I have added a
detailed problem description on the aforementioned bug.

Would like to get some attention from people who might know more about
this, and see if I need to create a brand new bug report or if that's
okay to work through the existing bug.

Also, any suggestions where else to look to find any clues that can
help resolve the issue or identify what's causing it are highly
appreciated.

Kind regards,
Garry Filakhtov
