I updated my 'mule' Sierra computer and there were no issues.
This is an h87 series running Clover with standard kexts from ~2017.

Then my production computer. It gave Kernel Panic on the second boot.
This is a Z97 running 580 video, Lilu and Whatever Green and Lilu related Kext stuff.
Something gaged big time, either/or with video or sound drivers.
Run in safe mode.
Reapplied 2019-004
Computer boots normally.
Reboot give Kernal Panic.

OK, load Recovery Mode and restore.
Gottcha-> Recovery Mode Time Machine AND Restore from Internet are both broken.
So I ran in Safe Mode for a couple days.

Recovery Mode is on boot disk, but I also have a Recovery Mode on a data disk.
Using the Recovery Mode on data disk immediately from reboot of loading 2019-004 in safe mode I was able to find Time Machine and restore OS.
Then cleared caches and rebuilt kexts. (one symptom of this need was a runaway CPU on a couple of multi-core programs)
Everything is working again.

My question is what happened to Lilu and friends?
