[solved] systemd-gpt-auto-generator failed to dissect

hello,

When I enable a systemd service I get a:

# systemctl enable lightdm.service
systemd-gpt-auto-generator: failed to dissect: Input/output error

I've already reformatted my system and reinstalled, but the error keeps appearing, and i wipefs all like say in this post https://bbs.archlinux.org/viewtopic.php?id=184894

I precise that i'm on a ASUS x205ta, because it seems that this computer is a problem. i follow the instructions for my install.
https://wiki.archlinux.org/index.php/ASUS_x205ta

my /etc/fstab

$ cat /etc/fstab
#
# /etc/fstab: static file system information
#
# <file system> <dir>   <type>  <options>   <dump>  <pass>
# /dev/mmcblk1p2

# /dev/mmcblk1p1

my lsblk

$ lsblk -fs

mmcblk1p1    vfat         960E-DC53                            /boot/efi
└─mmcblk1                                                      
mmcblk1p2    ext4         bf3dffbe-a3c2-4306-a962-94b8db1baa7c /
└─mmcblk1                                                      
mmcblk1boot0                                                  
mmcblk1boot1                                                  
mmcblk1rpmb

i searched for a fix to this issue, but am unable to find anything. Thank you all for your help.

Re: [solved] systemd-gpt-auto-generator failed to dissect

Please use code tags node quote tags for commands plus their output.  What version of systemd is the affected system using?

Re: [solved] systemd-gpt-auto-generator failed to dissect

You understood the meaning.
Looks like https://github.com/systemd/systemd/issues/5806 but 234.11-8 contains the patch to ignore mmcblk1rpmb.
From that link the boot parameter systemd.gpt_auto=0 should work around the issue.  However I recommend reporting the issue upstream.

Would call it more working around the issue than fixing it but if you are happy with the solution.
