Hello James,

Unfortunately I have'nt anymore -pa49 sources to check your patch but I still 
have the binary and a scsi terminator (which was removed for other test).

So I reboot with the vmlinux-2.4.9-pa49 end ending the scsi chain by the 
terminator and it works fine.

Thanks a lot for remarks and help,
        joel.
