I have to hard reset the machine here :( I can reproduce it with not too much IO. copying sources; make buildworld, ... I tried to do everything mentioned in the errata for 5.2(.1) but nothing helped. It also happened with DMA disbaled (an d I thing it logged PIO errors at that time). I am now going to build a world from NFS src to NFS obj to not have ATA traffic and to slow down things so this will not happen (hopefully). [ obj dir could be oon the same machine I suspect but the installworld will then most likely make the machine go berserk again ]. Are you running Release or HEAD ? If this isn't fix in HEAD yet I am very interested in every patches/things to try to fix this. The machine in question should become my new in house server and I do not like another IO problem once I night when backup is running... -- Greetings Bjoern A.
