I don't know if this is the cause but look for a zombie process. I had
something were A locked a file then forked B. A was "kill -9"'d but not
B. Somehow the lock was still held. The fix was "killall A; killall
B". I think what happed was A was a zombie waiting for B to die so it
could get its return code. Either that or the file lock was inherited
across the lock. Yeah I know sounds wrong but it worked.

Subject: [uml-user] F_SETLK failed, file already locked by pid 0
If I kill all tasks in that session I should see that file getting
unlocked right? Can we write a small kernel module that finds/unlocks
this file? Will that work? Is there any other way to get around this
other than rebooting the box or making a copy of root_fs and using that
for uml session?
I've built uml with 2.6.28 sources and running this on 2.6.11 kernel.
F_SETLK failed, file already locked by pid 0
Failed to lock '../bulk_fedora/root_fs', err = 11
Failed to open '../bulk_fedora/root_fs', errno = 11
ubda: Can't open "../bulk_fedora/root_fs": errno = 11

Hi,
http://uml.nagafix.co.uk/ redirects to the Overseas Procedures &
Surgery Ltd. website.
Maybe it has been hacked by someone.
That is the reason why you can't download the Fedora filesystem image.
