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: (cat /proc/interrupts) 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. Cheers Michael
