Armin, What is IRQ that shared???? I don't understand. In tracelog that you present I see that trigger IRQ 0 ( timer ) and scheduler change state of io-usb to RUNNING.

Seems so that io-usb is using InterruptAttachEvent ??

 And all.

IRQ

  0:    IO-APIC-edge  timer
  1:    IO-APIC-edge  i8042

Only these interupts are active in your kernel trace ... I don't see any real PCI interrupts! 
Is your Ethernet board broken ????????????

One of the shared interrupts is just the IRQ 0 ....
