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. Wassi

Hi, I just tested this on two of my older bcm47xx devices and I had no
problem with kernel 4.4.14 from LEDE with all the LEDE patches:
