Right, both of them are compiled-in by default.

I've patched it to allow "kb_ps2", and removed some stuff like INVARIANTS,
WITNESS, IPSEC, etc. in faint hope to eliminate problematic code path, but
it did not help: it still hangs, apparently in the same place.

I'll try to trim kernel config a bit more, and of course would welcome any
