I have captured such a lockup using the NMI oopser. Below you'll find the lockup fed through ksymoops. Note that after CPU3 locked up, CPU2 did too. But that lockup couldn't be captured anymore. Kernel is a monolithic 2.4.22-pre6. Problem also happened on plain 2.4.21. I can provide more information wrt. hardware, config etc. on request. Regards, -Udo. ksymoops 2.4.9 on i686 2.4.22-pre6.
