i run a machine with 4 dual gigabit ethernet cards utilizing 220.127.116.11.
All cards are PCI-E, one card is PCI-X, all Gigabit Ethernet from Intel.
This is working fine and stable if only the PCI-E cards are used.
If i try to capture packets on the PCI-X card, the machine reboots after
some seconds. I think i can rule out a hardware defect, as i actually
run two of this machines with equal hard and software and the problem
occurs on both machines. This is perfectly reproducible but i am unable
to debug this, as no (oops) messages are ever written to the syslog.
As the machine instantly reboots i guess there will be nothing valueable
shown on the display.
The interrupt layout:
16: 36 6 430 0 IO-APIC-fasteoi eth0
18: 33 5 305 126 IO-APIC-fasteoi uhci_hcd:us
b1, ehci_hcd:usb4, eth1
211: 2143 2210 127682 533 PCI-MSI-edge eth9
212: 5332 5818 10298 3594001 PCI-MSI-edge eth8
213: 129 46419 5525683 6 PCI-MSI-edge eth7
214: 13528 14184 34425 11239040 PCI-MSI-edge eth6
215: 50277 116 5821388 14 PCI-MSI-edge eth5
216: 595 590 347154 857 PCI-MSI-edge eth4
217: 48 153 5760 2653 PCI-MSI-edge eth2
The card in question is eth0+eth1. I even tried the following boot kernel parameters
with NO success.
nousb (don't need it, suspected the irq sharing as problem source)
pci=nomsi (this recommended my hardware vendor)
I need some advice, howto debug or solve this.
As i usually don't read the list, i would like to be cc'd.
