so here is the thing: after almost 2 days of installation tried to make an image with CloneZilla 2.0.5 and 2.2.15 and grub partition failed to save.

when loaded from gparted, it shows an error on the grub partition. message on the partition:

Code:

Unale to read a content of this filesystem! This cause might be a missing software package. the following system software required for FAT32 system support: dosfstools, mtools


Do not know is it safe to run a fix option there as in bad case i do not want to manually fix it.

message from clonezilla:

Code:

Run partclone: partclone.vfat -z 10485760 -N -L /var/log/partclone.log -c -s /dev/sda1 --output - | pigz -c --fast -b 1024 -p 16 --rsyncable | split -a 2 -b 4096MB - /home/partimag/Gentoo-KDE-2017-10-15/sda1.vfat-ptcl-img.gz. 2> /tmp/split_error.838mxC

Failed to save partition /dev/sda1.


again setup is exactly as in the handbook.

os itself boots fine.

google has only 1 post about this error above and really the suggestion is to try the latest clonezilla, which i used.

another reason why i actually blame this 4.12.12 release is because i did identical backup on prev 4.9.37 version and everything worked fine. i could successfully create a backup of all partitions, but after upgraded to 4.12.12, back up was not possible anymore.

and, when i tried to revert it to prev 4.9.37 version, source for that was not available anymore. like a real trap.

can anybody just boot from gparted and see what in there?

and support for FAT32 is in your new kernel too?
It would explain why it works with your older kernel (with FAT32 support), and why it fail with your newer (that lack it) kernel

I copied .config from old installation to the new 4.12.12.

Unless it's something different in the kernel config for 4.12.12?

Then what did you do to turn the 4.9.37 .config into a legal .config for 4.12.12?
How did you set all the new symbols?

intord,

"copied and merged my hardware settings" is required but not sufficient.
What about filesystem drivers and the kernel FUSE option, which is required to support user space implementations of filesystems.

Code:
source seek ERROR:Invalid argument
hinst that it may have left more detail in dmesg. Did it?

The thing is no. dmesg has a couple of errors about missing iwlwifi packages, but these packages (iwlwifi-8000C-29 and 30)looks like are not available yet.
Obviously checked all FAT 32 related settings in kernel, its there. Others you talk about is CONFIG_FUSE_FS=m and ...?

The message
Code:

source seek ERROR:Invalid argument


is from partclone actually, during creation image of a boot partition. images for other partitions are fine. os boots fine, overall nothing in the dmesg about wrong mounting/booting filesystems. one more suspicious thing in dmesg is about incorrect power management, can it be related?

so basically answering my own question: replaced hd. assuming that "SEEK to argument 11111111" means a physical sector on the hard drive which is not available

after install on a new hd, the issue does not appear anymore.
