Synopsis: amd64/9.99.68/GENERIC: xen/zfs - kernel: double fault trap, code=0

State-Changed-From-To: analyzed->closed
State-Changed-By: jdolecek%NetBSD.org@localhost
State-Changed-When: Mon, 29 Jun 2020 10:03:53 +0000
State-Changed-Why:
Actually usable kernel stack on amd64 is indeed 12 KiB, one whole page
is reserved for pcb, and one for redpage. Eventually we might want
to bump it if needed, but with the zfs stack fixes it seems fine for now.
Thanks for report and testing.
