I can confirm a similar (probably identical) issue on a Lenvoo x260 with grub 2.02~beta3-4 and beta3-5, but not with <= beta3-3.
Please see #852748 for all related information. Removing files form /sys/fs/pstore/ and even deleting other entries with efibootmgr manually didn't solve the issue. At this point, downgrading to grub2 2.02~beta3-3 or earlier is the only known workaround. -- - Harald Welte <lafo...@gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
