Hy...
I'd like to run the UML under the KERNEL 2.6, but I couldn't do it with
any of the versions. While it runs well under the kernel 2.4.24, giving
the outcome:

Look at the second item called:
FAQ: "I'm tracing myself and I can't get out"
There is an associated patch which needs to be applied to the UML
*guest* when running on a 2.6 host.

It's compliled into the Kernel, but it's still not works at all...

This patch cant be used with the -mm2 patch
Thx...:

The guest UML kernel??? Works for me. What guest kernel are you running?

That patch is absolutely not necessary to get basic uml functionality
working. It provides the possibility of better performance and more
isolation from the host, but it is not needed.

The guest UML using 2.4.23, and it works properly with 2.4.24 host kernel,
but not with 2.6.x ...

So we can't use this patch, but it's not work at all (without this
patch, too).

Is that guest 2.4.23 kernel stock, with only the mentioned patch (pasted
below) applied?
Are you absolutely positive that you rebuilt that guest kernel with the
patch???(I'm guessing that this is really the problem)
Are you still getting the same error message? ("I'm tracing myself...")

Hi...
It's also included in the host kernel (2.6.1-mm2) ...

You didn't answer any of my questions. I'm forced to believe that the
guest is either not properly patched, not properly rebuilt, or not
actually the version that you're running. Not much I can suggest other
than to recheck those things.
On the odd chance that 2.6.1-mm2 reintroduces a new version of this
problem that the mentioned patch doesn't fix, you could try the host
running stock 2.6.1.
Also, I inadvertently referred to stock 2.4.23, but of course you would
have had to apply a large uml patch to it in order to compile it at all.
Did you? If so, which patch, from where?

With host 2.4.24, yes. With host 2.6.x, you NEED to apply the patch to
the guest. Why is this not clear?

Hi...
But everything works on 2.4.24...!
