just a thought, but have you got a seperate IRQ number for each interface on the card ? recently had some performance (and time out) problems with multiple NICs. Check with ifconfig, interested to know
Three of the ports use IRQ 11 and the fourth uses IRQ 10. Note that

The problem is that most motherboards assign these shared IRQs when the BIOS initialises the PCI bus devices, long before the kernel takes control. I have at this very moment a working install of Mandrake 8.1 on a hard disk. If I plug it into an ABIT m/b, the NICS get separate IRQ's. Plug the same disk and NICs into a Gigabye m/b and they get a shared IRQ. You see this on the ROM bios initialisation screen, before any disk access. Is there any general way of re-assigning PCI bus device IRQs once the BIOS has done its stuff? I don't know of one. I once had to demote an otherwise perfectly good m/b to running Windows, because it persisted in allowing 2 NICS and the video to share an IRQ under Linux, and I was getting the timeout problems Malcom refers to when really driving both NICS hard.
