The best thing to do in such case is to press SYSRQ+P and to grab lots of different EIP addresses. If SYSRQ+P does nothing then it's an hard lockup and in such case the NMI oopser will help you.
So I suggest you to use the IKD patch and to enable only the NMI oopser. If at lockup time you won't see a stack trace, then press SYSRQ+P and report us the interesting EIP addresses (the System.map is necessary to resolve them later). Thanks.
