did someone of you notice reproducible crashes when loading the ethernet kernel module on R5/BONE? The debugger says:

That's all I get (with DEBUG=5). I cannot explain why this happens (ethernet_input does not close() anything, does it?). Probably it's


You may want to try to activate -fcheck-memory-usage and MALLOC_DEBUG=
15 - that should help detect any memory corruption. What might also help is to use bdb with single stepping.

Unfortunately, this did not help. But something else did:
Instead of killing the ethernet_input thread in ether_stop() I deleted the etherq and added queue-deletion detection code to the thread. But I doubt this is the real fix (though it does not crash, anymore). Is there a bug when killing a real-time kernel thread?
