Folks,
Can you please upgrade to a recent kernel?
A problem with ptrace has been fixed sometime ago, it might be what you're hitting.
The fix is part of v2.6.13:
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=bf85fa6c878aa3968df47d7f70a2b506c3e53b99
If that does not work, complain.
