Hi

After two days of narrowing down this error (I first suspected my lwIP/PPP port etc.) I narrowed down this stack corruption bug. I've written a little stress test which just writes data to the serial, while also receiving. When sending data from the host to the target, eventually a stack corruption occurs. For more details, and the source please see:

Nick, as you have written the kernel port as well as the serial driver I would be glad if you could have a look at it. I will do the same, but I guess you might find the source of the problem more easily :)
