Doesn't actually look all driver. The CD is good; works fine in this same drive with its own 2.0 kernel (and on other drives). Please note, this is a 386. Memory is good. dmesg and .config attached. Very long crash, but in case it's helpful. Happens when copying anything from the sbpcd CD-ROM. In between the "do_exit, do_divide_error, do_page_fault, do_page_fault" oopses it seems to be attempting to give me back a prompt (it's not succeeding). blk: request botched blk: request botched blk:
