Is this a hand compiled kernel?
Version?
Defaultconfig?
Kernel parameters?
Arch?

I got this error even while previously doing './kernel* ubda=./filesystem'. Right now, I am trying to run VNUML software. I have installed both the uml and vnuml packages. Put the kernel: kernel32.2.6.38.7 and filesystem: Debain-5.0-x86-root_fs

         Part of error log:
     
         i think the uml boot part starts only later, first there is some interpretation of the xml file i gave as an input to vnumlparser.
         $vnumlparser.pl -t file.xml

         error log:

This is not a message from UML.
