Re: [Xen-users] Re: [Xen-devel] irq 17: nobody cared (try booting with the "irqpoll" option)

Hello Keir,

today I got this error:

[ 1146.253445] Disabling IRQ #17

I am using xen unstable 20060610 with a 2.6.16.20 kernel.

I thought, that you made a fix for interrupt sharing between dom0 and domUs.


So what went wrong?

Thanks in advance,

Johnny
