So according to your comment #32 everything works as expected when the amd_sfh
module is blacklisted. Presumably this is causing memory corruptions (comment
#17).

The amd_sfh fix [1] landed on v6.11.4 and the commit message mentions:

"resolve memory errors, page faults, btrfs going read-only, and btrfs disk
corruption."

Thus my recommendation would be to update to v6.11.5, remove amd_sfh from the
blacklist, and see how it goes.

[1] commit c56f9ecb7fb6 ("HID: amd_sfh: Switch to device-managed
dmam_alloc_coherent()")
