Hey Avi,
I believe this will fix the issue (assuming the errata is the issue in
the first place).  You'll need to apply the patch on top of Linus'
latest code and re-enable the MPS tuning (as it is now off by
default).  This can be done by adding "pci=pcie_bus_safe" to your boot
args.

After thinking about it some more, a PCI quark is the correct way of
doing things.  We must always disable read completion coalescing due
to the possibility of hotplugging a device with a MPS of 256B.  Also,
I believe everyone will think this is much cleaner.

Agree.

Let me know how it goes and thanks again for testing this for me.

Works perfectly now.  Thanks.
