I'm confused:
Tue, 18 Jul 2023
. . .
=E2=80=A2 git: b36f469a15ec - main - zfs: set autotrim default to =
'off' Yuri Pankov
But you had written:
Dag-Erling_Sm=C3=B8rgrav <des_at_FreeBSD.org>
Date: Tue, 15 Aug 2023 17:37:45 UTC=20
The attached script successfully deadlocks 9228ac3a69c4
where:
Thu, 10 Aug 2023
. . .
=E2=80=A2 git: 9228ac3a69c4 - main - ixgbe: Add support for 82599 LS =
Kevin Bowling
(You had previously reported a poudriere deadlock there as well.)
Later on 2023-Aug-10 there is (about 11 or so commits later):
=E2=80=A2 git: cd25b0f740f8 - main - zfs: cherry-pick fix from =
openzfs Martin Matuska=20
=E2=80=A2 git: 28d2e3b5dedf - main - zfs: cherry-pick fix from =
openzfs Martin Matuska
I'll note there was also this:
Dag-Erling_Sm=C3=B8rgrav <des_at_FreeBSD.org>
Date: Sat, 12 Aug 2023 14:11:10 UTC=20
. . .
Trying to narrow this range down, I did not get a deadlock with
4e8d558c9d1c (10 June) but I did with b7198dcfc039 (16 June), albeit
after building ~1800 packages.
. . .
So the count seems to sometimes go well above 500 or so.
