Yes, it did. I can't say from which revision it's happening. I try to
keep kernel updated with each change related to this problem, as I
hope that it helps. But the problem is still present.

However, the kernels were built without INVARIANTS. Yesterday, I
prepared some debug patch which needed INVARIANTS anf KTR options and
the problem did not happen. The buildworld finished in about 15 hours
(taken from uptime) so it was about 2 hours faster then with kernel
before r285935.
