Xen dom0 "interrupt storm detected on "irq16:"; throttling interrupt source"

[Eggert, Lars]

Hi,

with Xen from git and a recent -CURRENT, I get "interrupt storm detected on "irq16:"; throttling interrupt source" messages on the dom0 console about once a second. irq16 is used for ehci:

# vmstat -i | grep irq16
irq16: ehci0                     1229805       6559

Any ideas?

Thanks,
Lars
