Hi,
I've been running Hauppauge PVR-150 cards in an expansion chassis and
seeing this kind of thing:
kernel: Uhhuh. NMI received for unknown reason 30 on CPU 0.
kernel: Do you have a strange power saving mode enabled?
kernel: Dazed and confused, but trying to continue
Or, on a different hardware type:
kernel: Uhhuh. NMI received for unknown reason b1 on CPU 0.
kernel: You have some hardware problem, likely on the PCI bus.
kernel: Dazed and confused, but trying to continue
When the cards are installed on a motherboard slot they're fine, but in
expansion chassis they really don't work well.
The theory is that the DMA controller has some problems.
Is there anyone seeing similar issues? Suggestions for things to try to
fix it would be most welcome.
Thanks,
Lou
