BTW I found two logs in the mail - panic-mtd.txt and lpss-pwm-patches-dmesg.txt The first set of log you gave - [ 2.658013] pwm-byt-plat 80860F09:00: PWM device probed: pwm_num=0, mmio_base=ffffc90001a46000 clk_khz=25000 [ 2.658223] pwm-byt-plat 80860F09:01: PWM device probed: pwm_num=1, mmio_base=ffffc90001a48000 clk_khz=25000 are seen in panic-mtd.txt and which is based on 3.10 kernel version as per the logs. Following one is seen in the other file which shows version as 4.5 [ 15.203281] [drm:pwm_setup_backlight [i915]] *ERROR* Failed to own the pwm chip: pwm_lpss So I am totally confused in the relationship of the logs. Look like they are from two different kernel boot instance of two different kernel version. Please provide me logs with latest run that you are planning to test now. put some prints in platform driver probe for LPSS pwm so that we can confirm that it found ACPI ID match or not. Also provide acpi table dump using acpidump.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
