I'm barely (if at all) familiar with GPIO calls, and I'm having a significant
difficulty with them and my National Instruments IEEE-488 Bus card.

It seems that something causes the call pbu_$enable_device to stop, and
spin its wheels for an indefinite period. The only way out is CNTRL-Q.
There is no possibility of setting a timeout for this call, and I'm
at a loss. The support people at National Instruments have no idea
what's going on, and don't seem to care (we already paid for the device,
why bother helping us?)

Does anyone have a similar experience with this board, or similar
experience with the GPIO calls?

It's a DN4000, sr9.7, National Instruments IEEE-488 instrument bus card
and software.

Oh, one more thing. High disk and CPU traffic on the node almost
guarantee the problem to happen.

Thanks to anyone who can help.
