(Especially the current transfer rate on Channel A Target 1 is
somewhat less than expected.)

Maybe there is a new driver by Justin Gibbs, but i didn't found
anything for the 2.4.21 kernel in
http://people.freebsd.org/~gibbs/linux/SRC/

Do You think the problem goes away by using a non SMP kernel?
(I have no problem to compile a new kernel, but the machine
is in a server room and i have to make an appointment with
the security guards to enter the room where the server is,
so i don't want to reboot this beast sitting 30 minutes
away from it...)
