Well just some feedback - I ran overnight on the -rt- kernel with no
wireguard... and it was clean and normal in the morning. Worked for a
couple of hours with and then fired up wireguard compiled from the
above commit - and its been running 10 hours now with no issues
whatsoever. dmesg nice and empty!

So many thanks - I think you nailed that one!

Its great to get a stable system again - brilliant work.

I love wg - and having it on android (user-space only because its a new
unrooted phone :( ) and Ubiquiti and LEDE... I'm sorted!

The GSOC projects are also very exciting prospects...
