Just to be clear, you're not using the usb virtualization stuff, just

During these tests, no domU was ever started.
Does anyone else see this interrupt storm with USB devices active?
Please can everyone check as I'll hold the 2.0.5 release (with USB
enabled in the default config) until we understand the scale of the
problem.
Also, note that I can get the same problem with bridging:
lots of timer interrupts
ip li set dev br0 down --> timer gets 30/s
ip li set dev br0 up --> timer goes crazy
