Hi, I have updated my box to kernel 4.6 bpo recently and my system initially failed to boot so I figured I could send a heads up.
I have my root partition on f2fs and it failed to mount. Apparently in 4.6 crc32 was renamed to crc32_generic [1,2], but f2fs wasn't updated to reflect that and it tries and fails to load crc32 (I think... I didn't investigate very thoroughly due to lack of time). To work around that, you need to add crc32_generic to your initramfs modules and flash that before updating. Just to spare you some time fiddling with those UART cables...
