@pazos: IIRC, that error is "normal", and related to the width/height swap because of the Landscape panel on the H2O. I certainly remember seeing it on my device as part of a normal and working boot process (quite possibly when pickel or nickel rotates the fb)
.
EDIT: Yup, fbdepth -r 0 -> fbdepth -r 3 triggers it, too.
Code:
[FBInk] Detected a Kobo Aura H2O (370 => Dahlia @ Mark 5)
Variable fb info: 1440x1080 (1440x2304), 8bpp @ rotation: 0 (Upright, 0°)
Fixed fb info: ID is "mxc_epdc_fb", length of fb mem: 6684672 bytes & line length: 1440 bytes
Current bitdepth is already 8bpp!
Switching fb to 8bpp (current bitdepth) @ rotation 3 . . .
Setting bitdepth to 8bpp
Setting grayscale to 1
Setting rotate to 3 (Counter Clockwise, 270°)
Setting rotate to 1 (Clockwise, 90°) to account for kernel rotation quirks
Bitdepth is now 8bpp (grayscale: 1) @ rotate: 3 (Counter Clockwise, 270°)
Variable fb info: 1080x1440 (1088x3072), 8bpp @ rotation: 3 (Counter Clockwise, 270°)
