This patch fixes the issue (``No available IRQ to bind to: increase
nr_irqs!'') that I reported in
<http://lists.debian.org/debian-kernel/2010/03/msg00665.html>, thus feel
free to add ``Tested-by: Thomas Schwinge <thomas@xxxxxxxxxxxxx>''.
I put this one commit on top of whatever Debian's
linux-image-2.6.32-4-xen-amd64 2.6.32-10 package has, and am now running
that one on my AMD Sempron system: uni-processor, no hardware
virtualization.
Regards,
Thomas
