I assumed the progress bar was some variant of fsck -C; in previous versions of Ubuntu, the progress bar showed a lot of detail about what the fsck was doing, although nowadays it's a simple percentage. fsck unexpectedly exiting at 90% would explain about half the symptoms I'm getting, though (although it wouldn't directly explain why the system would lock up rather than continue thereafter).
