  a fix for a deadlock for RFCOMM sk state change was posted last year already:

It seems it never went anywhere, unless I'm missing something. Is that
maybe the same problem or somehow related?

I mentioned this on the Arch Linux Matrix channel. The `linux` package
maintainer said they had encountered the same and added the linked
patch to the Arch Linux kernel package but removed it because it
wasn't merged (which explains why my issue went way then came back).
Anyway, we compiled a 5.19.8 `linux` package with the patch (which
fixes my issue) and they said they'll add the patch back to the linux
package.
Thanks for following up on this issue. I'd completely missed it until recently, and Luiz has suggested an alternative approach to fixing the problem here:

I'm planning to take a crack at it, but probably don't have the cycles for another week or so.

Best wishes,
Desmond
