[Solved] WRT1900ACV1 reboots: kernel 4.9

You are running the DIR-860L as well, right? How's the 4.4.67 kernel treating you? Are you using SQM by any chance? The current master branch and 17.01 branch both have issues with SQM on the mt7621 devices. It can cause stack traces and crashes that result in a reboot. Kernel 4.9 seems to have fixed it for me, but it is causing other issues for me. Was wondering whether kernel 4.4.67 is any good on mt7621 devices with SQM enabled.
