[yocto] [genericx86-jethro] core-image-sato - VFS: Cannot open root device "PARTUUID=8316.." or unknown-block(0, 0): error -6

[Simon Bolek]

Hello!

I am trying to install genericx86 core-image-sato on a atom-pc device with
80GB Intel SSD drive.
I have created an image with
bitbake core-image-sato
without changing anything in the kernel via menuconfig, etc.

ps. after installation I had to set /dev/sda1 to bootable with fdisk

After installation I have got this ugly error while booting the device.
PLEASE HELP ME!


"...
VFS: Cannot open root device "PARTUUID=8316.." or unknown-block(0,0): error
-6
Pease append a correct "root=" boot option; here are the available
partitions:
0100 4096 ram0 (driver?)
...
010f 4096 ram15 (driver?)
..."


I noticed that install.sh script is creating GPT
parted ${device} mktable gpt
not MSDOS as in previous yocto versions, e.g. fido.

Any hint is more than welcome. The device will just not boot :((((

Here are some details about the device:
