That dmesg starts some time after resuming, so I can't really see anything from
it. Please redo the test, and also to get rid of that hotplug noise in dmesg do
the following (preferably before loading i915):
intel_iosf_sb_write gpio_nc 0x5420 0x03010300
intel_iosf_sb_write gpio_nc 0x5440 0x03010300
