Here it mentioned something about mtx_* but, assuming this could be reproduced, I was so stupid that I didn't write it down... Took this out, rebooted and then tried kldload linux.ko and no panic :( Right now it looks like this won't be easy to reproduce... I will try to boot again and again until I get a new panic. Anything I should do, apart from dumbly rebooting until I get it again? I have INVARIANTS_SUPPORT and INVARIANTS compiled in, but no DDB, WITNESS or MUTEX_DEBUG anymore... Should I put those back?
