Heya all. I'm running RedHat 7.2 on an Athlon system that has been locking up at random intervals, sometimes 5 days, sometimes 5 minutes. I've gone through RedHat's update agent to try get the most recent kernel and packages to see if that will fix the problem. No luck, and I think (well pretty sure) that this is part of the problem. Grub is not reading the grub.conf file on boot up at all. There are 2 entries in the actual file for the new and old kernel, but it only displays the old in the boot list. I've even gone as far as renaming both of the entries in the grub.conf file. It still displays the old entry. I'm basically just trying to get it to boot the newer kernel to see if my lock up problem goes away.

It's the start plinking down things and see if it fixes things, and I know there have been issues with Athlons and Linux in the past. Once this is solved, I may be back with more issues dealing with the lockups if they don't go away, but first things first.

Thanks guys.

well you'll need to run grub itself to update the MBR, it won't read the conf file on boot....

Ok, not too sound any more stupid than I probably already do, what's the command for that? I read the man page and tried grub --config-file=/boot/grub/grub.conf and it simply gives the grub shell prompt. Is that all I needed to do?

Thanks a bunch for the help.

You don't have to run grub after you edit the grub.conf or menu.lst file. Grub reads the grub.conf or menu.lst file when it boots up. Are you editing the grub.conf file in the /boot/grub directory? Could you post a copy of your grub.conf file.
