Chris,
I have seen a patch circulated but pulled from 6.8.5 for this issue:
scsi: sg: Avoid sg device teardown race [ Upstream commit 27f58c04a8f438078583041468ec60597841284d ]
I think I have hit this issue in 6.8.4. Is there a patch ready for this bug yet please?
I merged the fix last week. I'm assuming it'll go to Linus soon.
