A panic also occurred on my Pentium (P54C) 66MHz, but backing identcpu.c to 1.79 didn't stop the panic. Here is the panic info, copied by hand. (I hope there are no typos!) Lots of 'ad1: timeout waiting for DRQ' followed by Fatal trap 12: page fault while in kernel mode fault virtual address = 0xc04e5000 fault code = supervisor read, page not present instruction pointer = 0x8:0xc01c56b0 stack pointer = 0x10:0xc49efd7c frame pointer = 0x10:0xc49efda0 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 = 133 (ldconfig) interrupt mask = net tty bio cam trap number = 12 panic: page fault Uptime: 12s Unfortunately, I don't have time right now to explore this further, but if more info is needed, just tell me what to do and I can help tomorrow evening (EST).
