Norster:

I'm running latest vanilla 21.02.1 with two vlans and freeradius3 installed, using dynamic vlans as in
https://openwrt.org/docs/guide-user/network/wifi/wireless.security.8021x

RT3062F crashes randomly with or without load. This does not occour on 19.07.8 with same configuration running stable for more than a week.
I tried this on an Arcadyan VGV7510KW22 o2 6431 with same outcome. FritzBox 3370 with same configuration runs stable with latest 21.02.1 but uses ath9k drivers.

removed: wpad-basic-wolfssl

installed: wpad-wolfssl, freeradius3-default

kernel partition on ZyXEL got right size:
NAND read: device 0 offset 0x60000, size 0x300000

Steps to reproduce: Boot device, wait for dsl sync, pppoe authentication done. rt2x00lib will cause kernel panic within 10 Minutes.
