panic on boot (1.7.2 & 1.8.2)

[spamwax]

I was using 1.7.2 and everything was working just fine. Then I used App Store to apply Apple's security update (2019-01) and the panic started to happen.

On first restart, I got the black screen message saying that computer had to be rebooted due to an error, after which I can get to login greeting. However after a short period of time (15-45s) the reboot happens and I get the black screen message again.

So I decided to upgrade to 1.8.1 and still save issue! Issue persisted even when I turned off all HDDs in the pools.

I used my TimeMachine backup to restore the system to the state before Apple's security update hoping it will fix the issue, which it didn't :( So at this point I'm stuck!

The kernel panic log as a gist is here.

Not sure if this is relevant, but I installed 1.8.2 however the above log shows some 1.8.1 versions for net.lundman.spl and net.lundman.zfs
