Juan, After last night updates I had a broken boot again, this time I noticed it stopped while setting the camera input. It just hang for a while and then jumped to initramfs prompt with a timeout message that it couldn't load the root drive ( the specified uuid device could not be found). I unplugged the camera, rebooted and it worked fine. This also happened last week, now it works even with the camera plugged in, so I guess this is a bit random.
