OK, the "irqpoll=1" option does help here. Although this message is obviously scary:
Misrouted IRQ fixup and polling support enabled This may significantly impact system performance
And the "pci=nocrs" option does Really Bad Things to the display at boot-time.
So what is "irqpoll" actually doing, please? Is it just a temporary workaround for a driver bug?
Thanks, Chris
