The problem still happens. irq 18 is dsiabled every now and then.
This time on different, new hardware.
The motherboard is now a Gigabyte F2A85X-UP4.
Camera is the same pwc cam.
Recently I removed the USB printer that was attached to the same USB

So probably it is not a hardware issue related to board or printer.
How to proceed next?

Firstly, what does /proc/interrupts say?
Secondly, try building a kernel with the patch below and
CONFIG_USB_DEBUG enabled. Let's see what the dmesg log says when the
problem occurs.

I just booted into 3.6.7 with the patch:
# dmesg|sort|uniq
ohci_hcd 0000:00:12.0: IRQ: 24 8000005a
ohci_hcd 0000:00:14.5: IRQ: 24 8000005a
#
So what does this mean?
I did not get the `disabling irq` yet.

It means your system was working normally. Which you already knew,
because the IRQ didn't get disabled.
