RHEL SMP kernel on Sun Fire V40z

I installed RHEL 4 ( kernel version 2.6.9-5.EL ) on a Sun Fire V40z server ( 2 * dual core CPUs).

Two kernels appear on the GRUB menu, the 2.6.9-5.EL and the 2.6.9-5.smpEL.

If the first run, no problem at all, but I can see only one CPU in the /proc/cpuinfo file. If I boot from the latter, the systems hangs up. In fact I need to run the SMP kernel to make use of the 2 CPUs.

Can anyone help in how to run the SMP kernel?

Thanks

Hello,I would recommend that you use a RedHat forum or newslist instead. This is not a hardware issue.Most contributors use Solaris on SPARC, some on X64, that's reason why you shouldn't expect a fast answer.Michael

Check the grub configuration file, and you can compile your own custom kernel and enable smp. I would look at the smp kernel configuration file. It could be an issue with dual core compatibility, does the system panic or just hang?

I agree with you Michael, but I am posting out of curiosity.
