Does the background fsck process continue to run, or does the whole
system come to a halt? If the fsck process continues to run, what
happens when it eventually finishes? Is the system still dead, or
does it come back to life? If the system does not come back to life
can you get me the output of `ps axl'? If not, can you break into
the debugger and get a ps output? (You will need to have the DDB
option specified in your config file).

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.
Thanks,
-Archie
