Well, you have a mixed system, so it's quite possible PMAZ-A support does
not work reliably anywhere. I don't have such a card, but specs are
available and the support code is about one screen long. So it should be
fairly trivial to verify -- I'll look at it.
Also you have a KN05 system, which doesn't help, unfortunately. The KN05
module implements aggressive posting of uncached (read: iomem) writes (see
also /proc/interrupts on your system) and synchronization primitives are
non-existent. Since for half a year there is no agreement on how generic
synchronization should look like for MIPS, I'm more and more tempted to
add a local hack which at least will let DECstations to perform reliably.
It's quite possible the lack of synchronization is the lone reason of your
problems.
