[Bug 1496163] [NEW] i915 firmware is not copied to initrd

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Philipp Kern (pkern):

On Skylake, the skl_dmc firmware is failing to load. From dmesg:

[    0.728803] i915 0000:00:02.0: Direct firmware load for i915/skl_dmc_ver1.bin failed with error -2
[    0.728817] [drm:i915_firmware_load_error_print [i915]] *ERROR* failed to load firmware i915/skl_dmc_ver1.bin (0)

This means the GPU can't enter its lowest available power states, plus
many display hotplugging scenarios (that only the skl_dmc firmware can
handle) are broken.

On a whim I tried some other firmware versions:

1) pointed the skl_dmc_ver1.bin symlink to skl_dmc_ver1_18.bin (instead
of skl_dmc_ver1_19.bin)

2) downloaded the latest (skl_dmc_ver1_21.bin) and pointed the
skl_dmc_ver1.bin symlink to it

But neither corrected the situation.

Thanks!
