System freeze on Dell laptop caused by lack of efivars memory when installing grub or using efibootmgr

I encountered the problem several times while installing grub or using efibootmgr, until I was able to free up space in the efivars storage on my Dell laptop.

Because df /sys/firmware/efi/efivars showed a usage of 100%, I searched and found a solution.

The directory /boot/efi/EFI/dell/SOS contained a large number of language support subfolders for various languages ​​that are of no relevance to me.


Mod edit:- Removed duplication of content. No charge.

Solution with doubts:

After having deleted the majority of the EFI/dell/SOS language subfolders (except for en-US, en-GB, and my regional language) and restarting the system, the usage rate of /sys/firmware/efi/efivars had fallen from 100% to 34%. Since then, the system freeze issue has not recurred, and fwupdmgr get-devices no longer shows any Not enough efivarfs space errors.

After @Teo’s doubts, I now have doubts myself that deleting the files had triggered the reduction in NVRAM usage. I cannot prove it. Perhaps some kind of automatic garbage collection by the boot firmware occurred during the startup of the computer. That remains an open question. However, I rule out an interplay of several actions of my own. The problem has disappeared nonetheless.

Don’t want to hurt your enthusiasm, but it is a coincidence. The /sys… Is on the nvram, the /boot…is on the hard drive. So if you had efivars error you cannot fix it by freeing space on the ESP.

You probably had both of those problems (lack of space in nvram and esp), you fixed the esp space and around that time you did something else that fixed your nvram without you realizing it (like updating the bios, resetting it, deleting boot entries, turning off or changing secure boot mode, manipulation on the dbx with fwupdate, etc) and now you think the 2 are connected. I also can understand why you have this impression - install grub writes to both of this places at the same time and i can imagine the error messages are not exactly precise so it will error out regardless where exactly it cannot write.

But it is a coincidence and if you think and remember what else did you do around the time you will find what truly fixed the nvram space.

That was my opinion before, too. But it happened exactly as I described (delete files and reboot). And I didn’t do anything else – I didn’t even go into the BIOS. It might be specific to Dell computers that data from the ESP causes efivars to bloat during boot.

@Acor

A few quick questions:

  • What usage percentage does it now show (both the $esp and /sys/firmware/efi/efivars?
  • How much space is now available on /?
  • Are you using brtfs?

:point_right: Please provide a link to that solution. :eyes:


System information might be helpful: :point_down:


[Mini-HowTo] Provide System Information

Basic details provided by *-fetch type apps might give enough information for someone wishing to buy a computer, however, for Support purposes it’s best to ask your system directly.

Output of the inxi command will generate more useful and detailed information for those who may wish to help:


Suggested inxi command (use either):

inxi -zv8 (short-form)
inxi --filter --verbosity=8 (long-form)

Command output should be presented as pre-formatted text in accordance with forum guidelines. :eyes:


Running inxi within a chroot environment

  • Add --color=0 to the long-form command, or…
  • Change the short-form command to inxi -zv8c0

Add it to post #2 so it may benefit others.

The solution is my description in this post. What I found by searching the web was an AI hit of Google.

Thank you for explaining.

@Teo : It’s strange. I wanted to restore the ‘bad state’ from a tar backup as proof, but I didn’t succeed.

After having restored the dell/SOS language file to the original ESP path /sys/firmware/efi/efivars is still OK (35% usage) and not 100% as I expected.

Exactly as expected :wink:

But one sees from the df the esp space shrinked with about 6 MB so the restore was successful.
It just has nothing to do with the 150k nvram. Of which you now have plenty.

In my experience the biggest :poop: on the nvram ever were the misco$oft .dbx files, one of which was over 30 kb. That is how i managed to fill my nvram once. Resetting secure boot deleted it.

That is also an option that i thought of but i do not have experience with dell.
Anyways, be happy the problem is solved. You should be fine for years to come with 100kb free.

I own a Dell laptop too and I also have 100% usage there. But I never encountered any problems, and Manjaro rolls on it since 2020.

There is no such directory on my system, still df /sys/firmware/efi/efivars shows 100% without problem.

So now we are even talking about Dell computers in general? Honestly, I can’t see how this topic could help anyone, unless further system information is provided. For a start inxi -zv8, and as @Teo already noted I agree we have to consider that the given solution isn’t a real solution but some sort of fluke.

I have seen laptops with firmwares that incorrectly report the used nvram as the total to the OS. At 80k it was 100% used and writing was possible, at next boot it was 100kb 100% and still everything worked. Maybe this is the case here too. And after some firmware update or driver update this was just fixed and it now shows the real value. Who knows. (But of course if you had writing errors this was not your case).

If it helps:

By the way, efivars usage has climbed back up to 80% in the meantime. That is presumably because I ran updates using fwupdmgr.

If you don’t dual boot with windows or something using secure boot you can skip the humongous dbx. Those are revoked hacked Microsoft signatures…which show how secure is the secure boot.

Thanks! Good hint! I put DisabledPlugins=uefi_dbx into /etc/fwupd/fwupd.conf.

I hope the system freezing won’t happen again in the future on my Dell Inspiron 5625. I performed a BIOS firmware update today.

Please provide information that might be helpful to others – the basic point of a User to User Support forum.

By marking your post (immediately above) as the solution, perhaps you were attempting to infer that updating your BIOS firmware had solved your issues, however, it is unclear; you need to actually state it to leave no doubt.

If you are uncertain what actually solved your issue, please say as much, and the topic can be closed without a confirmed solution.

The marked solution has been removed.
