I've added my most recent crash dump, this time it occurred during a rm -rf * in /usr/src. I'm starting to despair here, is it hardware/software or what? ==============Previous message========================== Back in September I sent a message to hackers asking what people thought of the kernel panics I had started to get from around April on a somewhat random basis when my machine was under heavy disk load (buildworld, make clean of ports etc). It doesn't panic every time I hammer the disk, but only sometimes. This machine has tracked stable for over two years now. Its a fairly vanilla box from Gateway. I was lead towards a couple of PR's, both are still open. > > Can anyone tell me if this hardware or a real bug?

I turned it off on /usr and have continued to get panics. Can anyone give me any clue as to what might be happening? Software / hardware / anything? I enclose the (hopefully relevant) dmesg output and two kernel stack traces, both from the last few days. Last built world on Nov 12th. I've had four or five crashes since then.
