I just built my own 1u server, I am using a desktop motherboard in the server. After I first built the server I ran Centos 3.5 on the server and everything was fine. Every time I reboot the server it was fine. Then I installed Centos 4.1 on the server and when I went to reboot the server it hangs on the reboot. The only way it will reboot on its own is with the keyboard pluged in. I have the bios set to ignore the missing on keyboard on boot up. (Centos 3.5 reboots with out a keyboard with no problem) Anyone have any idea what might be wrong?
Everything shuts down fine then it gets to restarting system and then it freezes. If I plug the keyboard in after its booted up and then restart it, it still hangs. If I boot it with the keyboard pluged in and then remove the keyboard it restarts fine. As long as the keyboard is pluged in on the boot up its fine. I have no idea whats wrong.
If I just shutdown the server it shuts down fine. It only hangs on the reboot.
Soulwatcher1974 - I believe what we need to know is *specifically* does it get past the initial Bios/CMOS power on self test (POST) before it hangs; in other words, does it get to the point where the boot loader is called. If it does, then it would be a CentOS issue, otherwise it would be a CMOS config issue.
I think we were already clear about it hanging on reboot (not on shutdown). We are here to help, but if a question is asked and not answered, then the rest of us cannot necessarily assist you efficiently.
Personally I am leaning towards it being a CentOS 4 issue since you did not mention changing system boards or reconfiguring CMOS between it working on CentOS 3.5 and going to 4.1
Also have you read this CentOS bug topic regarding SMP version and KB/Mouse port being swapped (bug):
It never makes it to the boot loader. When the server is off and the keyboard is unpluged and I start it up it goes to the boot loader and starts fine. If I shut the server down it shuts down fine. The only problem I have is when I type "shutdown -r now". The server stops everything and when it says restarting system it just hangs there the boot loader never loads.
With Centos 3.5 it restarts just fine with out the keyboard pluged in. I havent made any changes in the bios sense I loaded Centos 4.1, everything is the same I havent added anything to the server.
P.S. Sorry for not being more clear about the problem.
Thats weard I pluged the mouse into the mouse port and rebooted the server and it reboots fine. Its defentaly a bug in Centos 4.1 I hope they fix it soon I want to ship the server off to the data center. Anyone know a work around fix for this problem?
Mice are dirt cheap, leave one attached since it appears to solve the reboot problem.... I know the DC probably won't want you to leave a mouse attached.... (bugs is the) Price to pay to be on the bleeding edge.... (sorry, couldn't resist the jab)
