    This worked! Both suggestion actually worked. First tried the
    buffersize change and it worked. Then I patched my kernel and rebooted
    and the new sg module also worked.


    In /var/log/messages there were no indications of anything not working
    for the scsi system. The only scsi messages occured when I inserted
    the scsi modules (device detected and stuff like that, no errors).

    Thanks again.
