Linux Freezes at Shutdown
 

Hello. Here's the situation: I recently reinstalled RedHat 7.2 to fix some problems I'd been having. I now have several new ones. For example, Linux freezes when I press Ctrl-Alt-Delete. It gets to a random point in the shutdown scripts, and then hangs. The only solution is to push the power button. Sometimes, like while I'm writing this on another computer, it freezes at Stopping atd:, the very first choice. It stops atd, then freezes. Other times it gets to Stopping IDENT services:, about five choices down. What is wrong, and how do I fix it?

PS: I just wanted to thank everybody in this forum for all their help. I would still be trying to figure out how to boot into linux if it wasn't for this forum! Thanks.

If you check the /var/log/ it should list boot and shutdown logs, it might give you a clue to where problems occur. Now, because the logs are somewhat long, you can narrow search down using grep or tail.

$more bootlog | grep date?

$more bootlog | tail -40

There is a little bit of research that must be done on each part. This is a useful trick as well. There is log that keep getting updated. To see if any error messages that pop up. Most be root to be able to view it.

tail -f /var/log/messages

If it is not software, then it might have something to do with hardware. From there, it could be the hard drive, memory, CPU voltage is of, or power supply. Even checking the CMOS / BIOS settings might

So, alot of areas to research. It could be a software bug or could be a hardware bug. Try it and see where it leads you...
