--- Comment #2 from ruben_at_verweg.com ---
I tried

* zeroing the log device
* ran bonnie++ -c 2 -n 2048:64:16:512 as a means to make sure any uberblock as
seen with zdb -lllu would not refer to any uberblock that might know about the
previous state, checked with timestamps seen in the zdb output.
  * Did this with prior attaching the zil vdev
  * Did this with after attaching the zil vdev
* completely resilvered the mirror the zil was intended for by breaking the
mirror one way and re adding a clean device again and after resilvering doing
it the other way around.

so my assumption is that this is not caused by misinterpreting data in either
the zil or somewhere in the uberblocks, but beyond, and does survive a resilver

Doesn't seem to be triggered in 12.2p4
