My host OS is linux-2.6.11.8 from kernel.org, whiching running in FC3.
My Guest OS is linux-2.6.11.8 patched by uml-2.6.11.8-bs5.patch.bz2.
But when I run the command ./linux debug in skas mode. It can't fire
up the debug xterm. When I do it in TT mode which is 2.6.9.1.667 in FC3,
the debug xterm appears.
Here is some information.

I wonder why It can't fire up the debug xterm. Thanks.
