Steve,
Do you use a 10k RPM SAS hard drive? Could you share that what test
tools(or test cases) are you using to do the block IO test? We have a
LSI SAS1068E chip and 10k RPM SAS hard drive in our lab. I'll find
some time to reproduce the issue and do some investigation.

The default 128, set in Kconfig (look at FUSION_MAX_SGE).It only set
to 40 when that is not defined. What is in your kernel .config,

I was doing some performance comparisons between the aic94xx sas adapter
and the mptsas (lsi1078 chip) and saw that performance was slightly
lower on lsi using the same drive. One thing I noticed the mptsas driver
was only setting sg_tablesize to 40 which restricts the maximum size of
the IO to
