Have you tested your driver against the -mm tree?

To the best of my knowledge the irq handling of your hypertransport card
is a complete and total hack that works only by chance.

In the -mm tree I have added a first pass at proper support for the
hypertranport interrupt capability.  As this code is slated to go into
2.6.19 could you please test against that?

I would have tested it myself except when I mentioned this earlier I was told
that your card does not actually implement the hypertransport interrupt
capability properly.  

The practical reason for pathscale to work on this is the genirq work
in 2.6.19 changes the internal implementation detail your
hypertransport card has been relying on to work so your hypertranport
card will not work without fixes.

Thanks,
Eric
