rpm -qa output for system not showing error

Description Ulrich Beckmann 2016-07-11 10:06:07 CEST 
Description of problem:
I invoked efibootmgr to test the recent upgrade of grub2-efi. I get an error message: Bus error (Core dumped).

The command itself worked as intended. grub works fine here. I could not see any issue in my LVM and btrfs multi-boot system.
 
The system is a Sony Vaio E Series SVE1713G4EW notebook (Bios: InsydeH20 Setup Utility Rev. 3.7.).

Best regards
Ulrich

What's the output of the following command?
rpm -qa '*efi*'|sort

Another Cauldron system on the same hardware that has not been updated since net-install on 29 June does not have this issue.

Comment 7 Ulrich Beckmann 2016-07-11 15:03:15 CEST 
The kernel module efivar is missing:

[root@localhost log]# lsmod | grep efi
efivarfs               16384  1
[root@localhost log]#

It worked before, and I did not see that any related package was gone. Btw, I use dnf as packagemanager.

Best regards,
Ulrich
Comment 8 Barry Jackson 2016-07-11 16:01:16 CEST 
That is the same as my 29 June system without this bug.

[baz@localhost ~]$ su
Password: 
[root@localhost baz]# lsmod |grep efi
efivarfs               16384  1

I think the efivars module is built into the kernel now so it won't be shown by lsmod.
Comment 9 Thierry Vignaud 2016-07-11 16:15:16 CEST 
This is due to the update of efivar to 0.24

Source RPM: efibootmgr-0.12-2.mga6.x86_64 => efivar-0.24, efibootmgr-0.12-2.mga6.x86_64

Comment 11 Thierry Vignaud 2016-07-11 17:03:59 CEST 
Fixed in efibootmgr-0.12-3.mga6

Resolution: (none) => FIXED
Status: NEW => RESOLVED
