Hi Hauke, I also had no problem with booting 4.4 on my bcm47xx legacy devices. I just tested again with LEDE's current trunk: [1] does not boot on WRT54GL As already said: if I clone the repo and build it myself, the device boots perfectly fine (on 4.1 and 4.4) Can you confirm, that [1] does not boot on your WRT54G/GL/GS? In my opinion it's hard to discuss kernels not booting as long as the builds are not reproducable or deterministic. Maybe we can first figure out why [1] doesn't boot on some devices. Best regards, P.
