My guess is "sometimes" in the above comment means "On sun4c/d/m".
If you wanted to test in 2.2.x without the aforementioned patch, you
might be able to do something like (specific to your sun4m):
if (sdev->irqs[0] == 0) {
sdev->irqs[0] = 0x35;
printk("qpti%d: Adapter reports no interrupt, "
"blindly assigning irq 0x35\n");
}
...and see how the rest of the driver likes your card. This is just off
the top of my head-- no guarantees, of course.
