Aha, I forgot to describe about making qlogic drivers as a module.
While I had been setting and testing SAN switch(Brocade, Gadzoox),
RAID with Qlogic 2100(or 2200A), I had the same experience that you
described in the previous mail, and solved the problem by patching
drivers/scsi/hosts.c as you did. It was a good solution.
But, I became aware of the convenience and flexibility of modular
drivers(or initrd) in this case.
Because, I thought, whenever I do the same test or benchmarking,
rebooting the system each is terrible.
In that method, I experienced no problem such that you described
in the previous E-mail.
