dmesg output

Hi,
the following is the output of "ls -l /lib/firmware/i915/":

lrwxrwxrwx 1 root root     19 Apr 17 09:31 bxt_dmc_ver1.bin ->

skl_guc_ver6_1.bin
-rw-r--r-- 1 root root 129024 Apr 17 09:31 skl_guc_ver6_1.bin

I have also checked the md5 (taken from 01.org) of skl_guc_ver4_3.bin and
skl_guc_ver6_1.bin and they are both correct.

Please find attached the dmesg output.

The i915_guc_load_status didn't change:

cat /sys/kernel/debug/dri/1/i915_guc_load_status
