What happens is that at first I can login, but the system seems slow. I then got as far as running 'top' but it never refreshed its display and subsequently all keystrokes were ignored. Changing virtual terminals still works OK, but they are effectively dead too. I'm imagining processes getting stuck on some lock one by one. Top did get as far as showing the background fsck process, which had a priority of -6 or something. The previous time it didn't even spit out a login prompt, but that may just be due to experimental noise. For me, it appears easy to reproduce... 1. Boot -current system 2. Pull the power cable out 3. Put the power cable back in 4. Let the box boot; it notes backgroud fsck 5. Login and try to do something I can give you more details about my system separately if you like.
