So you are saying that specifying ubd0= explicitly does _not_, in fact, fix
your problem?  Your previous message seems to have said that it did.

And this is the problem.  Presumably pid 26263 is the UML itself, and for
some reason the file isn't getting unlocked.

You may have another UML using that file. Perhaps you killed some of the
UML processes, but not all of them?

"ps aux | grep linux" will probably show a UML still running.

(This has always been the case for me, when I get the "F_SETLK failed"
message.)

This was after a reboot, not killing UML, so this same UML was able to lock
the file earlier, and no other UML could have locked it during that time.

All previous command lines I tried with ubd0=root_fs did allow it to 
reboot.  For some reason, this command line didn't work.  I have no idea 
why.

In that case, are you sure no other process was locking the file?

I'm pretty sure not.  Nothing else was mounting that filesystem, and 
nothing else should have been accessing the file.
