unfortunately, this one goes south on the HP Omnibook X14, and also on the Elitebook G1Q. After excluding a lot of other causes, like inverted resets and wrong i2c channels, I did a bisect and landed at this commit. Looking at it, I speculatively increased the firmware initialization delay to 200ms. To no effect. Reverting this patch "resolves" the issue. with best regards Jens
