I see that there is a patch in the latest kernel.
commit a1c473aa11e61bc871be16279c9bf976acf22504
Author: Benjamin Herrenschmidt <benh@kernel.crashing.org>
Date: Fri Oct 14 14:56:15 2011 -0500
pci: Clamp pcie_set_readrq() when using "performance" settings
I think, this will resolve the issue.
We are moving to the new kernel. Will check it there.
