Thanks for the link.  I'm afraid that your kernel module is simply
buggy.

First of all as I explained before the kernel must never wait.  It has
exactly the same effect as extending the receive queue length.

Secondly each of your user-space messages is producing a number of
replies.  This should be done as a dump operation.  If you do it as
a dump operation, then you will never get overruns because the kernel
never sends more than the user can handle.

I'm happy to help you work on this if you have questions.

Cheers,
