So, I tried to revert the backing_dev_info changes and dpkg-built an updated kernel. But that didn't work out. Either because it isn't the cause, or because I reverted too much or too little.
After several hours of normal-load uptime, a removal of the mysql data dir quickly caused a panic. I did not get a dmesg+dump unfortunately, but I'd guess the same problem still existed.
