Jan has a Baytrail tablet, while David has a Cherrytrail. David has a DSI display, I suspect Jan has too but no confirmation. Anyway, might be two things at play here. First, a bunch of fixes have recently landed in drm-tip branch of <a href="https://cgit.freedesktop.org/drm-tip">https://cgit.freedesktop.org/drm-tip</a> which fix stuff for DSI. You should try kernel built from that. Second, you should ensure you have these kernel config options set when building the kernel: CONFIG_PWM=y CONFIG_PWM_CRC=y CONFIG_I2C_DESIGNWARE_PLATFORM=y CONFIG_I2C_DESIGNWARE_PCI=y CONFIG_INTEL_SOC_PMIC=y CONFIG_DRM_I915=m</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
