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] Followed by the transmit queue timing out. This seems to hit randomly, sometimes it can take a day or so. A hard reset is the only way to recover networking. (Userspace is Ubuntu 10.04, kernel 3.9.0 rc5+) Cheers David Apr 7 12:26:09 david kernel: [156475.568257] ------------[ cut here ]------------ Apr 7 12:26:09 david kernel: [156475.568273] WARNING: at net/sched/sch_generic.c:255 dev_watchdog+0x250/0x260() Apr 7 12:26:09 david kernel: [156475.568278] Hardware name: To be filled by O.E.M.
