This bug has been copied from bug #541953 and has been proposed
to be backported to 5.4 z-stream (EUS).

in kernel-2.6.18-164.9.1.el5

Comment 6 George Herman 2009-12-11 16:28:43 UTC
We were able to trigger the issue on a Dinar with the RC1 kernel and a script similar to the one posted in comment #30 of Red Hat bug #541953. It took only a couple of seconds to take the box down. After installing and booting into the RC2 kernel (2.6.18-164.9.1.el5) we ran the script again. The box survived 2 hours of random CPU hotplug. It's safe to assume that this fixed the problem.
