Hello Michael,
The OpenWrt kernel is based on the mainline kernel plus some other patches we
maintain for memory footprint or features.
I suggets you disable mini_fo in the kernel configuration because it was
responsible for some memory corruption.
You could also have reported the bug to our bug tracking system at
https://dev.openwrt.org. You will see that there a lot of other people trying
to get AR7 work (better ?).
Best regards, Florian
