--- Comment #10 from Greg V <greg@unrelenting.technology> ---
(In reply to Mateusz Guzik from comment #9)

Rather than bisecting, I was rebasing my local customizations onto ZFS rela=
ted
commits.

Looks like the culprit is "Update OpenZFS to 2.0.0-rc3-gfc5966"!

Interestingly I've also found https://github.com/openzfs/zfs/issues/11108 <=
< a
recent issue mentioning non-canonical addresses (seems like Linux detects t=
hat
when handling faults), even if in a different context.

I'll report this to OpenZFS.
