The problem seems to be described by other people in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/297058 . After investigating for a while, I found the errata http://www.intel.com/Assets/PDF/specupdate/313057.pdf , see especially errata #19 which handles MSI. Is this something that is handled in the driver? I have disabled MSI interrupts by using "pci=nomsi" on the kernel boot line for now, and will see if it fixes anything - hopefully it does.
