[uml-user] UML check_ptrace ptrace_oldsetoptions failed

[Giovanni F. <gaf...@gm...>]

Hi again,

So, I downloaded and compiled linux 2.6.26 with ARCH=um, but when I
try to run it it says "Checking that ptrace can change system call
numbers...check_ptrace: PTRACE_OLDSETOPTIONS failed: Input/output
error".
