    Thanks for your /proc/interrupts file. You have a lot less IRQ
    sharing than me:

               CPU0
      0: 5484369 XT-PIC timer
      1: 13698 XT-PIC i8042
      2: 0 XT-PIC cascade
     11: 301909 XT-PIC uhci_hcd, uhci_hcd, uhci_hcd, Intel 82801DB-ICH4, eth0, yenta, yenta, radeon@PCI:1:0:0
     12: 14446 XT-PIC i8042
     14: 63403 XT-PIC ide0
     15: 21 XT-PIC ide1
    NMI: 0
    ERR: 0

    I wonder why the system has got such a high affinity to IRQ 11. I've
    never seen so much IRQ sharing before. 8-/

    I'm going to give it a try without the radeon DRM module.

    By the way, here's a log message from the system when it tries to come
    back from suspend:
