[20:29] <luc4> Anyone who knows if it is possible to install an old kernel like 4.19 in Ubuntu 20.10?
[20:29] <luc4> I'm referring to Ubuntu for Raspberry Pi sorry.
[21:21] <waveform> luc4, erm - good question. For the desktop image almost certainly not (or not with working KMS at any rate). On server I'd *guess* it'd be possible for debugging purposes but I wouldn't bet on absolutely all the hardware working (e.g. there might be a few cases like wifi modules not working on the later platforms)
[21:23] <waveform> oh, and come to think of it the ethernet device "moved" in the device-tree at some point in the 5.x series so if you were using d-t's from a later build with the earlier one I'd expect that to disappear too. Basically I'd hope it'd at least boot but "things" may be missing
[22:15] <luc4> waveform: thank you for the information. I may try then, thanks.
