I think I got the numbers right, but in any case, this is the gist of the error:
PANIC: blkptr at ffff88040b993640 DVA 1 has invalid OFFSET 36830022909049856
What was the last version of ZFS-on-Linux (that you were using) that
works?
Was that the only version of ZFS you had ever used?
Can you attach the output of:
sudo zpool status
sudo zpool upgrade
sudo zdb
I assume you have swap on ZFS and this is breaking when it tries to access the
swap dataset? If so, can you provide this output (substitute for rpool/swap as
appropriate), which you should probably compress:
sudo zdb -dvvvv rpool/swap
I'm not sure that'll be enough information (as I'm not expert enough to
debug at this level), but it should be a start for me to take this to
someone else.
If it is happening with swap, try moving the swap dataset out of the way, and
create a new one:
sudo zfs move rpool/swap rpool/swap-broken
sudo zfs create -V 4G -b $(getconf PAGESIZE) -o compression=zle \
-o logbias=throughput -o sync=always \
-o primarycache=metadata -o secondarycache=none \
-o com.sun:auto-snapshot=false rpool/swap
sudo mkswap -f /dev/zvol/rpool/swap
This will hopefully get you working again on the latest ZFS. If you keep
the old dataset around, then we may still be able to debug how this
happened.

Title:
Ubuntu 16.04.1 Install zfsutils-linux Panic Error, endless loop
Status in zfs-linux package in Ubuntu:
New
Bug description:
Fresh install of Ubuntu 16.04.1, installed all updates / upgrades for
system before installing zfsutils-linux. The install processes all the
way to Reached target Swap then has a PANIC error and loops endlessly.
There is a zpool there already (was) with 3TB of data on it. This only
happened after the system upgrade, so I reinstalled the boot drive /
OS to see if it was just a issue with that, clearly it's an issue with
the zfsutils-linux package for 16.04.1
Package version installed zfsutils-linux 0.6.5.6-0ubuntu12
Screenshot attached as I can't actually do anything once the boot gets
to this stage:
