Thanks for the solution...

Does this work whitout kernel? Would it be better to use event-flags?

Thanks

I am not registered for the mailing list, but peruse it once in a while, so I am not sure if my mail will go through to it. Feel
free to repost it if it doesn't.
What we did to fix the locking issue was change the mutex to a semaphore. See the patch. It seems to work reliably.


Cheers,

Derek
