    SubjectRe: BUG() in asm/pci.h:142 with 2.4.13 (cause found!)

    The cause for my problems with crashing kernels when accessing the tape
    drive were differences between the original external RAID that belongs
    to the machine and a temporarily, nearly equal, RAID that we attached while
    the original was send away for repair.
    The temp. RAID was Ultra3 160 and /proc/scsi/aic7xxx/0 showed me a cur.
    speed of 160 while the "old" and working one only did Ultra2 with 80Mbit/s.

    I don't know if it's a hardware incompatibility or if the Linux kernel
    drivers cannot handle this specific case.

    The problem exists in 2.4.11-pre6, 2.4.13, 2.4.12-ac6 and 2.4.13 with
    patched from axboa(?) and D. Miller.
