--Sig_/I1kt9lqEZfT7evbjkYjI0DA Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Using a kernel based on r292334, I got this panic while importing a ZFS pool with vfs.zfs.spa_load_verify_data and vfs.zfs.spa_load_verify_metadata set to 0. I've not been able to reproduce it yet and the changed sysctl's above may not actually matter (but I usually use the defaults). The pool has a single leaf vdev that is backed by ggatec which transfers the data over a slow and easily saturated connection (< ~120 kB/s up).
