If I'd read a bit further through my Monday morning INBOX I'd have
found:

which indicates that the bisector has fingered:
commit 99cb8f3e9af516954b2f2fba97ce1856e3d7b93f

Do full BREGS backup/restore for pmm, pnp, and irqentry_extrastack
Although these entry points only require backup and restore of the
registers that the C code clobbers, there is no harm in backing up
some additional registers. This allows the BREGS macros to be used
which makes the code a little more readable.
