Yesterday I updated my TD-W8970 using the master branch and ran into these crashes/fixes. I haven't seen these before, and I've been running various older revision from the same branch which included the ATF patches.

I switched to the lede-17.01 branch and the crashes are gone now. Uptime is ~15h where it didn't survive 5m before.

I guess it's because of
71e86199ff lantiq: enable SMP for XRX200
which is on master but not on lede-17.01 (but I haven't verified that)
