Is it possible for you to test a current kernel, e.g., v3.8? The bug may have been fixed between 2.6.32 and 3.8. If not, I'd definitely like to fix it in the upstream kernel so v3.9 would work out of the box. If you could collect complete dmesg logs from v3.8 both with and without "pci=nomsi", that would be very helpful. > The symptom appeared to be problems with the 10G ethernet card that produced > error messages about do_IRQ.
