SubjectRe: sym/ncr53c8xx phase error: Some progress

Hello,

I just mailed Shaw the following.
Could you give it a try. It is untested and, by the way, applies to
the SCSI code.

: This may well be a bug in the SCSI code.
: The following Code seems suspicious to me (scsi_do_cmd()/scsi.c)
:
: if (SCpnt->cmd_len == 0)
: SCpnt->cmd_len = COMMAND_SIZE(SCpnt->cmnd[0]);
:
: If cmd_len is not zero for some reason, it will not be loaded with the
: right value of the CDB length.

: You may want to try this untested patch and let me know how it make
: differences:) . IMO, if it boots it has chance to fix.
