Thanks,
 
that seems to be the reason. Xen kernel doesn't seem to deal with
sharing of an irq 

An analogue bug is bug 76 
(http://lists.xensource.com/archives/html/xen-bugs/2005-06/msg00074.html


  

Without nousb, do you see sharing of an interrupt line if you 'cat
/proc/interrupts' ?
    

Dell 2850.(hyperthreading disabled)


with usb a lot of sharing :

megaraid and usb4 ...

Dell 1850 : Just for some extra info  (Hyperthreading enabled) doesn't
seem to have that problem. ( another machine on the netw without xen,
just info) no sharing.

Here is /proc/interupts from my Dell 1850 without the nousb option (no usb driver in kernel)
