There may be a problem with the DMA transfer, maybe your IRQ and/or DMA channel setting is wrong? You should post the exact parameters passed to comedi_config, and the dmesg output of one test run. You could try using FIFO instead of DMA by passing -1 as the DMA channel. hth, Nils -- Institut fuer Schweisstechnik und Fuegetechnik (ISF) Pontstrasse 49 der RWTH Aachen D-52062 Aachen ISF - Welding and Joining Institute fon: +49 (0)241 / 80-96274 RWTH - Aachen University fax: +49 (0)241 / 80-92170
