https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html#id-1.6.6.4
describes a simple procedure with which one can test patches.
I've attached the above referenced patch and verified that it applies
(cleanly) onto a 6.1 kernel.

Bill: can you test this patch and see if it resolved the issue?

Yes, I can test it.  Mostly likely I will not get to doing that until 
Sunday
night here in California.  For sure Monday morning at the latest.

This took me longer that I wanted, but I have built kernels the 
following
kernels with the patch:

linux-image-6.1.0-15-amd64-dbg_6.1.66-2~afs1_amd64.deb
linux-image-6.1.0-15-amd64-unsigned_6.1.66-2~afs1_amd64.deb
linux-image-6.1.0-15-cloud-amd64-dbg_6.1.66-2~afs1_amd64.deb
linux-image-6.1.0-15-cloud-amd64-unsigned_6.1.66-2~afs1_amd64.deb
linux-image-6.1.0-15-rt-amd64-dbg_6.1.66-2~afs1_amd64.deb
linux-image-6.1.0-15-rt-amd64-unsigned_6.1.66-2~afs1_amd64.deb

I have installed 
linux-image-6.1.0-15-amd64-unsigned_6.1.66-2~afs1_amd64.deb
on a couple systems.  Things look fine, but the problem is intermittent
and I won't be convinced that it is fixed until there are no errors
for at least a day.  One of the systems uses kafs heavily so I should
see any errors fairly quickly.  I send an update tomorrow.

This patch resolves this bug from my testing.

The original bug was not intermittent, and the failure could be forced
on demand.  My reference to an intermittent problem was to another
bug altogether---apologies for the confusion.

Thanks. It is as well already queued for next stable updates so we can
fix this once we pick it up from there.

Regards,
Salvatore
