When .rc3 released I got this error message at kernel compile stage. And 
now, one more time, I got the same error message. It seems, still this 
compile problem couldn't fixed in .rc4. My config is attached. I'm using 
Kubuntu 7.10 with the latest updates.


Makefile:514: /usr/src/linux-2.6.25-rc4/arch/xen/Makefile: No such file 
or directory
make[1]: *** No rule to make target 
`/usr/src/linux-2.6.25-rc4/arch/xen/Makefile'.  Stop.
make: *** [conf.vars] Error 2
