Looking at your logs more, it seems that you're not building the axp20x mfd code into the kernel, as the help text for MFD_AXP20X_I2C i2c says: Note on x86 this provides an ACPI OpRegion, so this must be 'y' (builtin) and not a module, as the OpRegion must be available as soon as possible. For the same reason the I2C bus driver options I2C_DESIGNWARE_PLATFORM and I2C_DESIGNWARE_BAYTRAIL must be 'y' too. So please make sure you've those and that you've also enabled XPOWER_PMIC_OPREGION. Related: are you building i915 into your kernel, or is it a module. If it is builtin please make it a module, there may be probe ordering issues otherwise. This message: axp20x-i2c i2c-INT33F4:00: AXP20x variant AXP288 found Should be in your logs before any i915 drivers *and* the PWM error needs to be gone. This alone might very well be enough to fix this...</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
