this makes a difference for the USB interrupt.
And in addition unbind the unused USB port.

$ grep nbind /usr/local/sbin/tuning
### Unbinding devices
echo -n "0000:00:13.2" > /sys/bus/pci/drivers/ohci_hcd/unbind

With very old kernels my graphics shares the IRQ with my PCIe audio
card, with newer kernels it doesn't, but that still isn't a help,
I guess the 2 PCIe slots and the integrated graphics share one PCIe bus
that is split into 2 slots + the bus for the on-board graphics. I might
be mistaken, but something still seems to be shared, it doesn't matter
what slot I use for the audio card and using a graphics card instead of
the integrated doesn't improve it either.
