Problems (hard freeze) with Dual tuners HD3000s

pchdtv.com :: View topic - Dual tuners HD3000s: "Does either card share an interrupt (cat /proc/interrupts) with anything else?"

Shared interrupt looks like this:
10: 461353 XT-PIC usb-uhci, usb-uhci, cx8800[0], cx8800[1]

(int 10)

Solution: Swap cards/slots.
