Hi!

Short overview:
- Had CURRENT system from around September
- Upgrade on the 23th of December
- crashes in ZFS, see
  https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=261538
  for details
- Reinstalled from scratch with new SSDs drives from
https://download.freebsd.org/snapshots/amd64/amd64/ISO-IMAGES/15.0/
freebsd-openzfs-amd64-2020081900-memstick.img.xz
- Had one crash with
  sysctl -a
  https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276039
- Still see crashes with ZFS (and other) when using poudriere to
  build ports.

Problem:

I happen to run in several cases of crashes in ZFS, some of
them fatal (zpool non-recoverable).

The latest was:

panic: VERIFY(BP_GET_DEDUP(bp)) failed

cpuid = 29
time = 1704050745
KDB: stack backtrace:

before I had to nuke that pool and restart...

I already have

vfs.zfs.dmu_offset_next_sync=0

which is supposed to disable block-cloning.

Does anyone else see this with recent versions or is it just me ?
