[Xen-users] irq bug

[Stefano Pardini <stefanopardini@xxxxxxxxx>]

Hi,
after a few minutes of operation, the dom0 starts to go very
slow.Checking the syslog, I see the following error message.
what do you think?
Thank you!



Setting "irqpoll" on the grub linux line, does not fix the problem!

cat /proc/interrupts
