    You might find some luck by adding this line to ppa.c (pseudo-patch,
    you'll have to do it by hand):

    @@ -690,6 +690,7 @@ static int ppa_completion(Scsi_Cmnd * cm
                    cmd->SCp.ptr = cmd->SCp.buffer->address;
                }
            }
    + udelay(100); /* PJC */
            /* Now check to see if the drive is ready to comunicate */
            r = (r_str(ppb) & 0xf0);
            /* If not, drop back down to the scheduler and wait a timer tick */

    Add that line and recompile, and let me know if it works. It probably
    won't fix the problem entirely, but it would be interesting to see.

    Thanks,
    Tim.
