Don, many thanks for your extensive report.

Regarding building "java/openjdk7": that never did trigger a hard-lock or a
reboot on my system here, unfortunately. The Java compilations of different
ports don't care about processor limitations; they always use all available
cores - at least here during my poudriere runs. So this could help stressing
your system until crash.

Regarding "DragonflyBSD patch": okay, makes sense that this patch is not
needed/incompatible on FreeBSD. Thanks for the clarification.

Regarding building "lang/ghc": yes, that build always generates a "bus error"
on my Ryzen system. On my Intel system, that build is always successful. Maybe
expected behaviour due to wrongly optimized bootstrap.

Regarding i386 builds: interesting that there seems to be no problems in 32bit
environments. But I don't want to go back to 32bit. ;-)

Regarding serial console: thanks for trying that out - I fear that you won't
get any debug messages during the crashes/lock-ups though. But let's hope the
best.
