Comment 1 RHEL Program Management 2007-04-06 22:25:21 UTC

This bugzilla has Keywords: Regression.  

Since no regressions are allowed between releases, 
it is also being proposed as a blocker for this release.  

Please resolve ASAP.

Comment 4 RHEL Program Management 2007-06-20 12:31:26 UTC

This request was evaluated by Red Hat Kernel Team for inclusion in a Red
Hat Enterprise Linux maintenance release, and has moved to bugzilla 
status POST.

Comment 5 Don Zickus 2007-07-19 21:01:15 UTC

in kernel-2.6.18-30.el5

Comment 7 Mike Gahagan 2007-08-28 20:21:14 UTC

[root@test183 tests]# diff out.2.6.18-*
18c18
< PASS: frysk4330/stopkills
---
> FAIL: frysk4330/stopkills
[root@test183 tests]# echo diff out.2.6.18-*
diff out.2.6.18-43.el5 out.2.6.18-8.el5

the failure mode according to strace is the ptrace(PTRACE_DETACH,...) call is
failing with a -ESRCH (No such process), with the -8 kernel. Exits cleanly with
the -43 kernel
