RE: [Xen-users] GPL PV Intermitent Network Problems

["Nick Couchman" <Nick.Couchman@xxxxxxxxx>]

Deleted the network card and re-added it, and it is still using IRQ 5 and still showing the same behavior.

Interesting... you are using irq 5. Are you not running with apic=1 in
the config?

I suspect that the problems you are seeing are because you are using an
interrupt < 16, which behave a little differently than those > 16. On my
system (apic and acpi left at the default of enabled) the Xen PCI Device
gets IRQ 28 and all the sub-devices use the same IRQ (even though device
manager reports the IRQ as ISA).
