I considered disabling the zil but didn't think it would make a
difference (because zfs will most likely check if there is any data in
zil on startup anyway). I'll try it though!

Importing the pool results in the exact same problem. (I couldn't export
the live pool because the box paniced, but by making sure the vdev was
unavailable on zfs startup I could export the stale pool, enable the
vdev (by doing a "geli attach") and then I tried to import the pool. No
luck, same panic message.
