Sure. Will apply this evening. It may take several days before I can report back due to the intermittent nature of the thing.

Thanks

I'm been seeing some problems with my new ish AMD motherboard/processor
combo and networking (r8169). I see the following page fault :-

Apr 7 12:25:14 david kernel: [156421.436545] AMD-Vi: Event logged
[IO_PAGE_FAULT device=02:00.0 domain=0x0015 address=0x0000000000003000
flags=0x0050]

Can you give the hack below a try ?
