What update of Redhat you are trying. As per Sun, x2100 only supports Redhat 4 Update 2 while x2100 M2 supports Redhat4 Update4. http://www.sun.com/servers/entry/x2100/os.jsp Thanks!..... Bipin >>> knabe@xxxxxxxxxxx 5/7/2007 1:52:30 PM >>> I updated all of my servers over the weekend, and one of them would not reboot. The only way I could get it to boot sucessfully was to revert back to the previous kernel version. I am unsure what log information would be helpful in troubleshooting this, so if someone is willing to help me troubleshoot it, I will provide whatever they are looking for. The original kernel was 2.6.9-42.0.10.EL, and the new one that wouldn't boot is 2.6.9-55.EL. The hardware is a Sun X2100 with an AMD Opteron 148. All of my other servers are running opteron based processors, and I have never had an issue upgrading the kernel release on any of them.
