[Xen-devel] radeon in dom0/ivtv in domU: irq 16 nobody cared

[Mark Hurenkamp <mark.hurenkamp@xxxxxxxxx>]

Hi,


With a fairly recent (~march 29th) xen/next kernel and a recent  
xen-4.0.rc9-pre build, i still get
occasional 'nobody cared' messages on a IRQ which is shared between  
dom0 radeon
driver, and domU ivtv driver. Usually this happens while i'm working  
on the desktop,
and a recording is active in domU.

Is there something i can do about this?


Regards,
Mark.
