Thanks very much for that, it worked great! Would it be possible to give me
a brief explanation on how this achieves the hard lockup (i.e. what does it
actually do that leads to a lockup)?
The first version that you've sent didn't work for me.

The fact that my processor has a LAPIC considers it as an SMP (it has 2
logical cores but not 2 physical ones)? It's not a multicore processor
(Intel Celeron M 440) and I haven't configured my kernel with SMP.
