Problem with no options showing for kernels. |

Posted info to Fedora list, but haven't gotten any responses yet.
Had a 1 hour load sheading issue and building generator did kick in, and
USP isn't big enough to handle an hour outage. Afterwards, the grub menu
was showing no kernel options, just the memtest and g4l options, but they
are in the grub.cfg file. Was able to get the machine to boot, by bring the disk
up with the g4l kernel, and then after doing some test, found that remove
everything but the name on the menuentry line would make it show up and
then boot. The uuid of the root partition is fine, so I don't see anything that
would make the entries not show up. I recreated the grub.cfg by using
grub2-mkconfig -o /boot/grub2/grub.cfg, but it again resulted in no kernel
options, so had to make the changes again. None of the other 20+ systems I
have running Fedora 22 had this issue, but this machine did have a
motherboard failure recently, but replaced the board, and everything else
was the same. Booted fine after that change.
Below is the original message I sent to the Fedora list, and it has the grub.cfg
as I currently have it on the machine. It doesn't show the regular kernel
options, but after my g4l one is the one that works with just Fedora as name.
Thanks.
Had a load shedding issue that hit my college building at 2am and building
generator didn't kick in, and UPS didn't say up for the hour outage. Went in at
about 6:30am on Sunday to fix things, and found that one of my main servers
was coming up with the grub menu, but only the options for memtest and my
g4l special option were showing up. None of the kernel option would show
up? After booting with the g4l option with its kernel, I was able to look at the
grub.cfg file, and options are there in the grub.cfg file.
I was able to get it to load the kernel by copying the kernel options to the end,
and removing the extra stuff after the menuentry name?? I had also
commented out the load_video line, and switched, the linux16 and initrd16 to
linux and initrd, but don't think that was the issue, since after doing a reboot,
it wouldn't show the opiton until I changed it to just
menuentry 'Fedora' {
I though it might be the blkid that was off, but it seems to be correct.
Below is the current grub.cfg that I had made on the machine using
grub2-mkconfig -o /boot/grub2/grub.cfg
Originally, it went thru, but the reboot showed only the memtest option, and
the g4l option, and I did the coping of the line, and modification to get it to
boot.
Had a 7am meeting that I ended up being late for, since I could get the
machines all up quickly. Machine is now running, but still don't know why the
regulare grub menu options are not showing. The 20+ other machines seem
to have the grub working just fine. This machine did recently have a
motherboard failure, and it was replaced, but everything else was the same.
Below is the grub.cfg and the output of blkid??
Thanks.
