Subject: E1000 (PCI-E) doesn't work on nforce430, MSI issue.

Hi,

Is it a known problem?
Linux 2.6.24.2, ASUS M2NPV-MX mobo, nforce 430 based, two PCI-E x1
E1000 cards, 32-bit kernel, default e1000 driver (PCI IDs disabled in
e1000e).

Don't work by default. "pci=nomsi" fixes the problem.

82572EI Gigabit Ethernet Controller (Copper) (rev 06)
Subsystem: PRO/1000 PT Desktop Adapter

(8086:10b9 subsystem 8086:1083)

grep eth0 /proc/interrupts 
 20:       1945          1   IO-APIC-fasteoi   eth0

(without "pci=nomsi":
221:          0          0   PCI-MSI-edge      eth0)
