At the moment /dev/cd0 isn't connected in but I've rearranged things so that the other 17 drives are cd1 to cd17. I've put a CD into the first 10 and started to mount them and "du" the contents. Numbers 1 to 5 worked fine but when I du'ed /dev/cd6 I got: (cd6 is the 3rd drive on the 2nd bus if that helps) fatal trap 12: page fault while in kernel mode fault virtual address = 0x6ed32c48 [0x2b478] fault code = supervisor read, page not present instruction pointer = 0x8:0xf01244dc code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 203 (du) interrupt mask = bio panic: page fault I then reset and tried again and got the du off cd6 without the other 5 mounted. Remounted the other 5 again, tried the du on 6 and bang - basically the same printout apart from the address in [ ]. Does this help at all? I was going to ask whether I just needed to bump up "DK_NDRIVE" but I guess that's a bit naive?? The drives are set to use 2048 byte sectors - is that any problem?
