If so, I'd urge you to examine both of the interrupt handlers; it feels like one of the drivers is not playing well with the other when an interrupt occurs on both at the same time. Or maybe it's a problem in the arch code where it doesn't call both handlers? In any case, trying a recent 2.6 kernel may give better results.
