Oh, so it's not arm64, which has the most juicy changes this time around. Can you try the following "manual bisect" for me? First test f69e342eec008e1bab772d3963c3dd9979293e13 to see if that works. If it doesn't work come back as I'm a bit lost :) If it does work, try b5c58b2fdc427e7958412ecb2de2804a1f7c1572 next, if it doesn't work can you send me your dmesg? We'll then work from there.
