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 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 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. =3D=3D=3D Mark Millard marklmi at yahoo.com
