Subject: kvm-vm boot fail: ttm_bo_cleanup_memtype_use?

Hey,

I am getting a bug arround:

"Workqueue: events ttm_device_delayed_workqueue [ttm]"

when using Linus' kernel with HEAD:

commit a180bd1d7e16173d965b263c5a536aa40afa2a2a (HEAD -> master, origin/master, origin/HEAD)
Author: Linus Torvalds <torvalds@...ux-foundation.org>
Date:   Sun Jul 4 16:12:42 2021 -0700

while booting a kvm vm.

The config is attached, and the bug messages are:
