UEFI - requested Map

Hello.

I installed Arch Linux yesterday and my System is working, but everytime I boot the following "Error" message comes:

[0.000000]efi: requested map no found
[0.000000]esrt: ESRT header is not in the memory map.

I have a Lenovo Ideapad 100S and configure the EFIBOOT with the following commands:

gdisk /dev/sda
o //new Partition table
n // new Partition
1 // Number 1
// Default first sector
+550M //Last sector
ef00 //Partion type
... // Creating SWAP and System
w

//Format EFI Partition
mkfs.fat -F 32 -n EFIBOOT /dev/sda1
//Creating /mnt/boot and mount /dev/sda1 on It
mkdir -p /mnt/boot
mount -L EFIBOOT /mnt/boot 

//Install needed packages for UEFI BOOT after change arch-chroot to /mnt
pacman -S grub efibootmgr dosfstools gptfdisk
//Install and configure Grub
grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=arch_grub --recheck --debug
grub-mkconfig -o /boot/grub/grub.cfg

These are my EFI/Secure Boot related commands during the installation. Where is my fault?
Happy about solution suggestions.

Re: UEFI - requested Map

At first glance, there seems to be a discrepancy in your commands:

mkdir -p /mnt/boot
mount -L EFIBOOT /mnt/boot 

grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=arch_grub --recheck --debug

Re: UEFI - requested Map

You mean because I set the efi-directory to /boot instead of /mnt/boot?
Thats because I arch-chroot to /mnt after mounting the partitions.

Re: UEFI - requested Map

I installed Arch Linux yesterday and my System is working,

So the system is booting correctly?
Those messages are from dmesg / journalctl -k ?

Re: UEFI - requested Map

Yes, It is booting "correctly". After the messages gdm appears.
And yes I copied the messages from dmesg.

Re: UEFI - requested Map

I installed Ubuntu gnome to test if the same massage appears. "Unfortunately" not.
So I installed Arch again double check every command while installing. Same message again.

I am doing It wrong, again and again Hmm... I am installing Arch with Wiki instructions. There must be more people with this Error Message.

Re: UEFI - requested Map

"requested map not found" comes from
https://git.kernel.org/cgit/linux/kerne … .8.13#n413
note the spelling difference from "requested map no found"
"ESRT header is not in the memory map" from
https://git.kernel.org/cgit/linux/kerne … .8.13#n256
If the system is working does it actually matter that these errors are generated?
I would not take the generation of these errors alone as evidence that you have done anything wrong.

Re: UEFI - requested Map

My first guess is that this is a firmware problem.

"My first guess ist that this is a firmware problem."
After that Statement, I hoped that my firmware "problem" (https://bbs.archlinux.org/viewtopic.php?pid=1679016) would solve this thread, too.
But looks like the firmware is installed. And the Error messages are still there.

"If the system is working does it actually matter that these errors are generated?"

I just want to install the system right one time. I think if I ignore those errors, I will stumble over problems from time to time.
