This one doesn't seem to have a console log.

Kernel panic here but not arm64 specific. It looks like a possible
scsi_debug teardown race. IIUC, b402a0dce64a ("scsi: scsi_debug: Fix
create target debugfs failure") fixes the synchronization before target
creation but not on module exit. The bug is probably from f084fe52c640
("scsi: scsi_debug: Add debugfs interface to fail target reset") if I
look at the recent fix.

Adding some linux-scsi people. The panic from the log:
