My machine has recently upgraded itself to a new kernel and now it won't boot. It fails after several seconds telling me that various UUIDs don't exist. But they're the same devices that another kernel does run from. The new kernel which doesn't work is 3.14.18-3 and the one that does work - I'm using it now - is 3.12.25-3.
I would have said that if the various partitions do exist, then it *should* work so where do I start trying to fault-find this?
