FYI - I did try it earlier this morning with 2.6.14.2 and it
did *not*
fix the issue. I will see about updating to 2.6.15-rc1-git4,
and trying
that again...
Ok, that make sense, I see your patch is handling mpt_config.
So with the patch I provided at the link above, can you apply
this patch over that. I've added the sync code in mpt_config.
Please let me know the results. I also have a tool called
getspeed that I can send you. It dump's the programmed
speed the devices were negotiated at.

Hi Eric -
I just added in this patch on top of the previous one (again, on
2.6.14.2) and it worked just fine - I'm getting full U320 16-bit
transfers. I use
% /usr/bin/sginfo -t 0x19,0x3 -Xz <dev>
to determine this - prior to these patches I would see some of these:
/dev/sde 255 0 0 0 2 0 0
Now I see:
/dev/sde 8 127 1 87 2 1 3
Which is *much* better!
Thanks!
Alan
PS. Expanded -
