Please attach the output from acpidump
Please verify that you are running the latest BIOS,
and if not, upgrade, re-test, and attach the new acpidump
output along with the new output from lspci -v
The failing device is this one, yes?
05:01.0 Ethernet controller: Intel Corporation 82541PI Gigabit Ethernet
Controller (rev 05)
[ 1.130160] e1000: Intel(R) PRO/1000 Network Driver - version 7.3.21-k8-NAPI
[ 1.130254] e1000: Copyright (c) 1999-2006 Intel Corporation.
[ 1.130365] e1000 0000:05:01.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
IRQ 17 is not on a programmable PCI interrupt link,
so that can't be the problem...
Conceivably it is simply hard-mapped in the PRT to the wrong IRQ...
What does /proc/interrupts show?
If your spray packets at the interface, does some
other devices interrupt count go up?
a random guess...
What happens if you boot with "pci=nomsi"
