The good news is, this post is not debug-related as much as it is an introduction and query while I download the latest DENX kernel(only place I know that has the DWC_OTG driver). I've been working with a Kilauea dev board and have had lots of trouble when I plug in a sierra-wireless modem dev kit on the USB. It goes fine untill I actually try to communicate(pppd or minicom) with the little bugger and then my IRQs go through the roof. And they only calm back down after I shut down my communicaiton channel. I've solved this issue with our board, and was wondering if it has since been fixed (I'm running 2.6.25-DENX). I don't want to waste the board's time with a patch that is no longer necesarry. -- Hunter Cobbs --00163642719eb5f806046a8c40dc Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Hello everyone,
