Yes, I just reposted it to roland, but it was the same.

If you get this with the patch applied, then the problem is very serious. I 
thought the patch would have been able to fix this second part (when I got 
this, I received two panics, first the "Kernel mode fault" and then this 
"Kernel BUG" (for more info look where it says: comments explains what 
happens).

You said you provide the kernel at:
http://www.stearns.org/uml/

Since I'm not able to upload a kernel while you seem to have broad band, could 
you please (if it is not already so) provide a kernel with debugging symbols 
enabled and showing this bug to Jeff Dike, since it seems he cannot reproduce 
the bug?
