Hi,
I have a board with an AMCC440 processor, running RAID5 using the
async-tx interface. In general, it works well, but I have found a test
case that consistently causes a hard lockup of the entire system.
What makes this case odd is that I have only been able to generate it
when accessing

I grabbed the latest from denx.de, but unfortunately, to no avail. The
dd test still hangs pretty much immediately.
Thanks nonetheless.

Hello Justin , Three seperate single runs of bonnie(*) .
Please note , the linux-2.6.23-rc6 , Concerns your email of
this weekend about Subject: Bonnie++ with 1024k stripe SW/RAID5
causes kernel to goto D-state .
No lockups or hangs were noticed .
So you got 2x with those optimizations I mentioned? Nice, did you
previously get that speed, or?

Yes , the opt.s did get me a ~ 2.5x speed up . This array (afaicr)
has never had that high a thruput . But I am
