Comment 36 for bug 330824

I haven't tried with rc5 but I can't trigger the lockup in rc3 or rc4 at all (after much trying too!). Going back to ubuntu 2.6.28 I can still trigger it almost immediately.

http://kernel.ubuntu.com/~kernel-ppa/mainline/ doesn't have any more built kernels lower than rc3 so I'm stuck unless someone can point me to a tutorial on compiling rc1 from source.
