This bug has been copied from bug #485323 and has been proposed to be backported to 5.3 z-stream (EUS).
in kernel-2.6.18-128.1.7.el5 you can download RPMs of recent 5.3.z kernels from http://people.redhat.com/jpirko/.el53z/
comment in #5 is wrong, should be: bug is verified by running test case in https://bugzilla.redhat.com/show_bug.cgi?id=485323#c1
This bz addresses ia64 arch. There's not mentioned anything about x86. I think that this suppose to be taken as a separate issue and a new bz should be opened for this (x86 arch). Thanks
