revision 356776 breaks booting for powerpc64 users. It reportedly works fine on 
POWER8, but I get kernel panic on POWER9 (Talos II) right after the usual 
warning: WITNESS enabled. Kernel panic is uploaded to

@jeff
Since you commited this patch, can you fix this issue or revert this commit?


Is this still a problem for powerpc64? I've not seen
anything looking like a direct response or like a
status update for this.

I do see arm report(s) of problems that they also
attributed to head -r356776 . But I've no clue how
good the evidence is generally. An example message
is:

https://lists.freebsd.org/pipermail/freebsd-arm/2020-January/021069.html

But one part of that is for specifically for going
from -r356767 to the next check-in to head: -r356776 .
That problem likely has good evidence for the
attribution to -r356776 .


I will give current a try and report back. However I am hesitant to do so as I have a working G5 right now.

For science ... I will do the experiment.
