SMP vs. RAIDframe?

[Holger Weiss <lists%jhweiss.de@localhost>]

I finally got around to trying an SMP kernel (4.99.72 as of a few days
ago) on my Ultra 80 (4x450 MHz).  Many thanks for all the efforts.

However, all filesystems (FFS with neither softdep nor WAPBL) are on a
RAIDframe mirror, and for some reason, booting GENERIC.MP leads to a
dirty parity.  During the parity rewrite, the system will freeze within
a few minutes; that is, I cannot BREAK into DDB.  If I mark one of the
RAIDframe components as failed using raidctl(8), the system seems to run
happily until I generate more or less heavy disk I/O.

So, I'm not sure whether this is RAIDframe related, and I wasn't really
able to gather useful information yet, but I'd be interested if running
RAIDframe mirros on SMP kernels works for others if such problems are
expected.
