> drm/i915: Introduce a gmbus power domain
>
> gmbus also needs the power domain infrastructure right from the start,
> since as soon as we register the i2c controllers someone can use them.
>
> v2: Adjust cleanup paths too (Chris).
>
> v3: Rebase onto -nightly (totally bogus tree I had lying around) and
> also move dpio init head (Ville).
>
> v4: Ville instead suggested to move gmbus setup later in the sequence,
> since it's only needed by the modeset code.
>
> v5: Move even close to the actual user, right next to the comment that
> states where we really need gmbus (and interrupts!).

> Meelis, can you pls retest this one?
I also confirmed that my 865G chipset computer was suffering from the
same problem and the patch also helps on D865GLC mainboard with my
userspace that autoloads eeprom driver.
