This patch = fixes it for me: https://github.com/openzfs/zfs/pull/15251 . >=20 > Mark, could you please try the patch? If all goes well, this will end up reporting that the poudriere bulk -a is still running but has gotten past, say, 320+ port->package builds finished (so: more than double observed so far for the panic context). Later would be a report with a larger figure. A normal run I might let go for 6000+ ports and 10 hr or so. Notes as I go . . . Patch applied, built, and installed to the test media. Also, booted: # uname -apKU FreeBSD amd64-ZFS 15.0-CURRENT FreeBSD 15.0-CURRENT amd64 1500000 #75 = main-n265228-c9315099f69e-dirty: Thu Sep 7 13:28:47 PDT 2023 = root@amd64-ZFS:/usr/obj/BUILDs/main-amd64-dbg-clang/usr/main-src/amd64.amd= 64/sys/GENERIC-DBG amd64 amd64 1500000 1500000 Note that this is with a debug kernel (-dbg- in path and -DBG in the GENERIC* name). Also, the vintage of what it is based on has: git: 969071be938c - main - vfs: copy_file_range() between multiple = mountpoints of the same fs type The usual sort of sequencing previously reported to get to this point. Media update starts with the rewind to the checkpoint in hopes of avoiding oddities from the later failure. . . . : [main-amd64-bulk_a-default] [2023-09-08_16h31m51s] [parallel_build:] = Queued: 34588 Built: 414 Failed: 0 Skipped: 39 Ignored: 335 = Fetched: 0 Tobuild: 33800 Time: 00:30:41 So 414 and and still building. More later. (It may be a while.) =3D=3D=3D Mark Millard marklmi at yahoo.com
