Where'd my second proc go?

Dual-P3-850. Bios reports both procs. 2.4.21-ac3 reported both procs. 2.4.22-rc2-ac1 only shows one. The lilo used to have a "maxcpus=1" append but I removed that and I tried changing it to 4 even. cat /proc/cpu only shows 1 still.

Pushing to the latest 2.4.22 kernel would be a nightmare as that means another testing cycle and 2.4.23 will be out before it gets passed.

Thoughts?
Robert

It looks strange, can you boot with 'debug' kernel parameter and send the entire /var/log/dmesg

Thanks

I'll try and get a window, this is a production box so I can't keep rebooting it. just put 'append="debug"' in the lilo.conf and reboot? (headless server)

Yep, the other dmesg had missing parts..

Hmm could you try running the attached and sending the output, that might help if not, i'll need you to send over a dmesg from a working kernel.

Thanks,
