Well crap. That was _not_ virgin 6.1.0 after all, it was 6.1.0 with...

3959066b697b NFSD: add support for sending CB_RECALL_ANY

culprit, and intended to pop them off and rebuild, but they were in
fact in the booted kernel. Oh well, booboo could have a bright side.

Hi Mike-

I'm guessing your client mounts with NFSv4.x.

We've been chasing a similar problem for a few months, but for
lack of a solid reproducer, it has remained elusive.

We believe the problem was introduced between 5.19 and 6.0. If
you have a fairly reliable way to trigger the server hang, then
maybe a bisect would be possible?

Yes, mount says vers=4.2.

The 'solid' reproducer attribute is a bit of a problem, why I was
taking potshots at it. I'll try to sneak up on it.

I let my desktop box play server/space-heater for a long test session
of 6.1 with and without the above series: with, box bricked 3 times in
~5 hours, without, 0 bricks in ~6 hours. Box says woof -> duck ;-)

Given the similarity you mentioned, I wonder if my bug is perhaps your
sneaky bug rendered somewhat less sneaky by that series? One can hope.

Thank you for testing!

Not likely: we've seen problems since 5.19, and these patches were
merged in 6.2-rc.

So my question is whether you see a problem when only a1049eb47f20
is applied, or only when all three are applied?

Seemingly the latter.

Stuffing the other two into 6.1 sans a1049eb47f20 seems to agree that
the problem lies therein.
