(In reply to Robert William Vesterman from comment #1)
If microcode size is more, than staging_slop option, it overwrites memory after
staging area (where kerlen, modules, microcode, memory tables are written). It
grew with every microcode version and finally destroyes something critical in
the memory. Probably in previous snapshots you had smaller microcode file.
 Set staging_slop at least 8Mb+microcode size:
exec="staging_slop NNN"
in loader.conf
