Subject: soft lockup with pre-rc1

I pulled down Linus tree today and did some testing with some filesystem
related patches. Running xfstests against ext4 in a VM, and I hit this:

Last commit in my tree is this:

833477fce7a1 (origin/master) Merge tag 'sound-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

I also have some filesystem related patches on top of this. inode-
>i_version patches mostly -- nothing that should effect things at this
level.

config is attached.
