Hi,
I'm getting the following in dmesg with 2.6.19-rc5 and 2.6.19-rc6
kernels quad
opteron server running 64bit kernel, and the network card gets disabled.
On identical server running 32bit kernel, same cards, same slots, same
configuration running rc5 I see no errors.

its an e1000 adapter on irq 48

got quite a few interrupts considering there are no link events in
your logs for eth4 or eth5
there are vlans on the interfaces.

um, GSI 48 is the only interrupt using IOAPIC[2], could that be related?

how come you aren't bringing the interfaces up? At least I don't see
any link messages. We request the IRQ only at open. Something else is
causing interrupts on the e1000 devices' lines.
The bonding driver is using the eth0 and eth1 and is triggering the event:
e1000: eth0: e1000_watchdog: NIC Link is Up 1000 Mbps Full Duplex
bonding: bond0: enslaving eth0 as a backup interface with an up link.
e1000: eth1: e1000_watchdog: NIC Link is Up 1000 Mbps Full Duplex
bonding: bond0: enslaving eth1 as a backup interface with an up link.

I suspect the IOAPIC code or ACPI code.
