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
