Hello,

 

I have recently moved from a CentOS5.8 to a CentOS7 cobbler server but have been observing very bazar behavior when some of the servers are rebooted. Once the server gets past loading the pxelinux.0 loader file and reading the /var/lib/tftpboot/pxelinux.cfg/<file> and boots to local the systems just hang. My work around was to copy over the pxelinux.0 file from the previous server and now it works fine. Any thoughts or suggestions that would help troubleshooting would be greatly appreciated.   

 

Thanks
