Actually after two days of banging on this issue I have reached two 
resolutions.  

1. Flashing to latest firmware (3.08.00.016) seems to have solved it.

2. If you cannot flash firmware, you can use 2.6.16.38 kernel from Xen 
3.0.4.  I tried this kernel with Xen 3.1.3-rc2 and it works.

Sounds a bit strange to me, but nice if it helps for you...
I have a 9500S-12 and the latest firmware is 2.08.00.009 - which is flashed
on my controller already.

That's right, 2.6.16 on 3.0.4 works very well. I wouldn't call
it "solution", but it's a nice workarround, until someone cute fixes this
problem.

After two days of banging on this issue I have reached two 
resolutions.  

1. Flashing the 3ware card to latest firmware (3.08.00.016) seems to have 
solved it with all kernel versions.  This is highly recommended that you 
flash your firmware before continuing as I believe this to be the root cause 
if all the problem.

2. If you cannot flash firmware, you can use 2.6.16.38 kernel from Xen 
3.0.4.  I tried this older kernel with Xen 3.1.3-rc2 and it works.  Primary 
drawback (aside from the obvious) is that you may have to compile in network 
driver, ect.
