Please describe "old system" and "old software".

Well, you get other interrupts and therefore it seem to be specific to
the CAN hardware and the bus/slot it is connected to. You say that it
works with your 2.6.35.7 kernel but does not with 2.6.38.8 on the
*identical* hardware, right? Then I would check the kernel configs for
PNP related differences.
