NI-6052E problem: DMA overwrite of free area from makoto fukushima on 2005-11-19 (gmane.linux.comedi)

Hello-

I am new to comedi and having a problem with NI-PCI 6052E.

When I try to collect data with a high sampling rate (~300kS/s),
the program "crashed" and stops collecting the data and
/var/log/messages says:

kernel: ni_mio_common: DMA overwrite of free area.

It is working fine with a lower sampling rate (~200kS/s). What
would be a cause for this?

I am using:
comedi           0.7.70
comedilib        0.7.22
Linux kernel    2.4.22

Thanks,

Makoto Fukushima
