Subject: Re: r8169 regression: UDP packets dropped intermittantly
Francois Romieu <romieu@...zoreil.com> :

If you can crash your system at will, you may apply the patch below to
da78dbff2e05630921c551dbbc70a4b7981a8fff ("r8169: remove work from irq
handler.") parent (aka 1e874e041fc7c222cbd85b20c4406070be1f687a) and
build it in a current tree (say 4.2).
If it works it will be easier for me to compare behaviors in current
tree (especially as none of my current test boxes wants to boot with
my own ga311).
How much memory and CPU may I rely on in your test computer ?
