Doubtful. Octanes use hundreds of watts and aren't very fast compared with modern systems. They are indeed big endian, however. Debian used to have some Broadcom SWARM (BCM91250A) systems. They're bootable as big or little endian (controllable with a jumper on the motherboard). I have some that I attempt to use for Gentoo, but they're unstable and their kernel support seems to be totally unmaintained. Aurelien, do you know what happened to those systems? I don't see them listed here: https://wiki.debian.org/MIPSPort#Build_daemons_.26_porter_boxes (Gentoo would love your hand-me-downs if you're no longer using them :) > Last I checked, stretch kernels did not work on these machines, but I would > like > to be wrong. > Is the problem with the linux port, or is it related with Debian's compilation > options?

The maintainer of T2 Linux (René, Cc'd) has a YouTube channel in which he demonstrated an Octane running a modern (4.8?) kernel he had patched. I have not seen evidence of those patches going upstream though. As far as I know his work is in a significantly better state than that of Joshua's (from Gentoo).
