Message-ID: <1456516685.9718.5@x201s.roaming.asbjorn.biz> Date: Fri, 26 Feb 2016 19:58:05 +0000 From: Asbjørn Sloth Tønnesen <ast@...erby.net> To: intel-wired-lan@...ts.osuosl.org Cc: netdev@...r.kernel.org Subject: BUG: ixgbe_select_queue: general protection fault in v4.4.3 Hi, It seams that v4.4.3 doesn't like having lots of vlans, the fault occurs shortly after enabling forwarding, with in this case just 350 net_devices defined. The server is now running a known good v4.3.3. The NIC is a X520-DA2. The issue quite reproducible, but I will first have some spare hardware to do further tests on some time next week.
