The log shows that it was assigned legacy IRQ 19 (shared with USB) but then switched to MSI IRQ 29. But I don't understand why that would happen. It's probably irrelevant, but can you try removing 'acpi_osi=Linux' from the kernel command line? Also, can you test Linux 3.1 from the testing or unstable distribution? You will need to upgrade initramfs-tools and linux-base, but nothing else. Ben. -- Ben Hutchings Design a system any fool can use, and only a fool will want to use it.
