e100 in 2.6.15 fails unless irqpoll ist used

[Nils Rennebarth <nils.rennebarth@packetalarm.com>]

Hi,

An upgrade from 2.6.14.3 to 2.6.15 on my testmachine disabled my network cards: 
no packets are sent or received.

There is the following in dmesg:

usbcore: registered new driver usbfs
usbcore: registered new driver hub
USB Universal Host Controller Interface driver v2.3
irq 11: nobody cared (try booting with the "irqpoll" option)
 [<c012ae21>] __report_bad_irq+0x31/0x77
 [<c012aef4>] note_interrupt+0x75/0x99
 [<c012a9f0>] __do_IRQ+0x65/0x91
...

Rebooting with irqpoll will make the network cards work. The above message will 
appeare nonetheless.

lspci output:

What does irqpoll do?
Any more info needed?
