Linux - Kernal Panic on reboot with Asterisk


I just installed the lastest Asterisk on CentOS 5.0, however whenever I have asterisk running and a system reboot occurs I get a kernel panic. If I reboot the system without asterisk running, the reboot works fine without the kernel panic.

Any ideas on what could be the problem. I check the /var/log/message file for any info on hte panic but there is no record.
