So, it tries to set VBI on interface 5, with obviously fails. It seems that the code is identifying a wrong PCB for this device. That's said, the probe logic is doing a crap job by allowing to go past the array.

Just sent a patch detecting this condition and aborting the probe. That solved the OOPS, but, of course, the device doesn't work. See the logs.
