UML error - apps killed 50% of the time

[Adam Nielsen <a.nielsen@shikadi.net>]

Hi all,

 From my other message I am trying to get a UML kernel running again after an 
OS upgrade, but I am unable to get it working again (on the original machine 
this time, everything is 32-bit.)

When I boot the kernel normally I get tons of error messages, but if I boot it 
with "init=/bin/bash" I can get a command prompt up.  Unfortunately most of 
the time my apps break:

$ ls
bin  boot  dev  etc  home  lib  lost+found  mnt  opt  proc  root  sbin  sys 
tmp  usr  var
$ ls
Killed
$ ls
bin  boot  dev  etc  home  lib  lost+found  mnt  opt  proc  root  sbin  sys 
tmp  usr  var
$ ls
Killed
$ ls
Killed
$ ls
bin  boot  dev  etc  home  lib  lost+found  mnt  opt  proc  root  sbin  sys 
tmp  usr  var

What's going on?  My host dmesg says things like this:

vmlinux[6300] general protection eip:b7ea5124 esp:1785bdfc error:0

Why doesn't UML work any more?  It's running the same filesystem and apps as 
before.  Any help would be much appreciated, I've wasted hours on this now :-(

Thanks,
Adam.
