I got the following panic on 10.0-CURRENT from two days ago
while receiving an incremental snapshot to a certain pool:

The incremental was created with:
zfs send -i @2013-03-28_14:21 tank/home/fk@2013-04-01_12:31
piped through mbuffer and received with:
zfs receive -v -u -F rockbox/backup/r500/tank/home/fk
Reading the incremental directly from a file triggers the
panic as as well, but sometimes it takes more than one attempt.
The offending sa_magic in the panic message is always the same.
The receiving pool appears to be okay:
fk@r500 ~ $zpool status rockbox
pool: rockbox
state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not support
the features. See zpool-features(7) for details.
scan: scrub repaired 0 in 0h3m with 0 errors on Mon Apr 1 13:57:35 2013
config:
NAME STATE READ WRITE CKSUM
rockbox ONLINE 0 0 0
label/rockbox.eli ONLINE 0 0 0
errors: No known data errors
The feature that isn't yet enabled is lz4 but after upgrading
a copy of the pool the panic was still reproducible. On the
receiving side gzip compression is enabled.
