I built 2.3.0-rc0 but also added RH patches which applied (mainly for
pc-q35-rhel7.1.0 machine type support) from

After suspending and restoring VM prints the following and hangs:

[root localhost ~]# [ 43.595571 irq 23: nobody cared (try booting with the "irqpoll" option)

Any idea why? I will try with a pure qemu w/o RH patches later.
