I've seen the same panic on our Sun-2/170 running 4.0.1. "hat" stands for hashed address table, but beyond that I couldn't say. We have also had a wierd panic every time we boot our 2/120s under 4.0[.1]. Just before vmunix starts probing for devices, right after it sizes memory, we get a "panic: hat_unlock". After it (tries to) write a crash dump, it (auto)boots normally. We haven't ever seen this on our 2/170, though. Could it be a CPU board rev problem which only our ancient 2/120s have? @alex
