Description henrik.johansson.kank@gmail.com 2020-04-01 07:40:44 UTC
1. Please describe the problem:
After upgrade of kernel, the running kernel aren't changed

2. What is the Version-Release number of the kernel:
5.5.8-200.fc31

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :
The problem may have existed since Fedora 29.
After upgrade to Fedora 31, the network didn't start, had to boot with an old kernel.
The network problem was solved in bug 1783358.
When I noticed that Fedora started an old kernel, I started to build a new grub.cfg with grub2-mkconfig


4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:
dnf update

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:
I'm running latest kernel after updating grub.cfg

6. Are you running any modules that not shipped with directly Fedora's kernel?:
Not what I remember

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.

Thanks for your report. This sounds more like a grub2 issue than a kernel problem.

Can you see the grub2 menu when you boot? If not, try pressing or tapping the "Esc" key while booting to see it.

> I started to build a new grub.cfg with grub2-mkconfig

If /etc/default/grub has

GRUB_ENABLE_BLSCFG="true"

you shouldn't need to do that.

With BLS enabled, all the grub2 menu entries are in separate ".conf" files in:

/boot/loader/entries/

"BLS" means "Boot Loader Specification".

Comment 3 Steve 2020-04-01 17:00:10 UTC
Could you post the output from:

$ cat /etc/default/grub

For comparison, here is what the default /etc/default/grub file has in it after installing F32 from a live image:

$ cat /etc/default/grub.ORIG 
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved

Could you try testing with these settings added back in (They are in the default grub.cfg in Comment 3):

GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_DISABLE_RECOVERY="true"

There shouldn't be any "menuentry 'Fedora'" items in grub.cfg.

Could you post your grub2 package info:

$ rpm -qa grub2\* | sort

That all looks good. In my F31 VM:

$ rpm -qa grub2\* | sort
grub2-common-2.02-106.fc31.noarch
...

> Should create a new grub.cfg with grub2-mkconfig or edit grub.cfg directly?

Always use grub2-mkconfig. Please clarify -- have you been trying to hand-edit /boot/grub2/grub.cfg?

That looks good. I believe the Windows menuentry is needed because there is no ".conf" file for it in /boot/loader/entries/.*

You can check the differences for yourself with:

$ diff -u grub.cfg.EXP1 grub.cfg.20200401 | less

Now for the BIG QUESTION: When you boot with grub.cfg.20200401 (renamed), do you see a grub2 menu entry for 5.5.11-200.fc31.x86_64?

* You could put a ".conf" file for Windows in there if you wanted and set GRUB_DISABLE_OS_PROBER=true in /etc/default/grub.
  Disclaimer: I haven't fully tested that.
  See "info grub2", "6.1 Simple configuration handling".

There is a possible problem -- you might need to run grub2-install. Javier writes in Bug 1713902, Comment 13:

"The other option is to set GRUB_ENABLE_BLSCFG=true in /etc/default/grub and re-generate your grub.cfg. If you have a legacy BIOS install, then it may be needed to update the GRUB core.img with grub2-install /dev/X (where X is the block device where the GRUB was installed)."

Before you do that, let's try to get the grub2 version:

1. Boot to the grub2 menu.
2. Press "c" to get the grub2 command prompt.
3. Type "version" to get the version.
4. If the version is displayed, make a note of the version numbers -- there are two, "GNU GRUB" and "Compiler version".
5. Type "reboot" to get back to the grub2 menu.

Actually, more pertinent is whether this command works: "insmod blscfg". That's what let's grub find the menu entries:

$ grep -n -A8 'blscfg command' grub.cfg.20200401

Thanks. Bugzilla generates a beautiful side-by-side diff display for that.

As the diff shows, grub.cfg.20200401 uses the "insmod blscfg" command. If the "blscfg" grub2 module is not in your grub2 configuration, grub2 will not be able to load the BLS menu entries from /boot/loader/entries/, and will probably drop you into the grub2 rescue shell.

So, before attempting to use grub.cfg.20200401, please:

1. Make sure you have a recent Fedora Live image (on a USB flash drive or a DVD) that you can boot from.
2. Using your current grub.cfg, please check that the "insmod blscfg" command works from the grub2 command-line (Comment 12, Comment 13).

That is all intended to make sure that you can boot successfully from grub.cfg.20200401 and have a way to recover if not.

Thanks. There should have been some numbers and a date after the "Compiler version". Those grub2 version numbers are not always completely precise.

Could you also try the "insmod blscfg" command? That just loads the "blscfg" grub2 module and should give an error message if it does not exist.

There is no error message, so that also looks good.

Thanks for testing and for your report. That's great!

I believe this bug is the same as:

Bug 1713902 - With Fedora 30 the kernel update does not update the grub configuration anymore 

That's against "grub2", so could you change the component of this bug to "grub2"?

I'm closing this since as far as I can tell the problem was that the installed GRUB was too old and it was needed to update the installed GRUB with grub2-install as mentioned in:
