Possible. I cannot really try as the smallest config would be a single CPU board housing 2 CPUs. Or do we honor the maxcpus (or whatever it is called..) SRM variable? > I don't suppose you could map the pc to a file and line number in the > kernel.debug? (gdb kernel.debug .... (gdb) l *0xfffffc0000491ae4) I'll have to move the disk back to the dual CPU DS20 on which the same GENERIC booted OK. But that can be done (tnx to the StorageWorks SBB that houses the disk ;) > A stack trace might be useful too... I know... But I need to find the time work work this thing between normal work :) Next week we will start moving our complete machine room to another building so that probably also won't help. Anyway, it is not too urgent, given the relative lack of Tlaser owners in the FreeBSD population at large.
