i915 kbl_guc_ver9_14.bin does not load

[Andrew Crouthamel]

The provided i915/kbl_guc_ver9_14.bin does not load when configured to do so . If the file is replaced by manually installing with the included script from 01.org, it loads properly: https://01.org/linuxgraphics/downloads/kabylake-guc-9.14

Before:
GuC firmware status:
        path: i915/kbl_guc_ver9_14.bin
        fetch: FAIL
        load: NONE
        version wanted: 9.14
        version found: 0.0
        header: offset is 0; size = 0
        uCode: offset is 0; size = 0
        RSA: offset is 0; size = 0

After:
GuC firmware status:
        path: i915/kbl_guc_ver9_14.bin
        fetch: SUCCESS
        load: SUCCESS
        version wanted: 9.14
        version found: 9.14
        header: offset is 0; size = 128
        uCode: offset is 128; size = 142272
        RSA: offset is 142400; size = 256

Status changed to 'Confirmed' because the bug affects multiple users.

Which release are you running, and what version of linux-firmware do you have installed? As far as I can tell the only two releases which contain that file (artful/bionic) have the exact same file as the one at the link you provided.

This is 17.10 with linux-firmware 1.169.3. It does seem odd, is there something else the install script from 01.org does that maybe fixes it?

[Seth Forshee (sforshee)]

I'd be very surprised if there was, more likely the file from our package got corrupted somehow on your machine. You could force reinstallation of the package (sudo apt install --reinstall linux-firmware) and see if that fixes the problem.

This appears to work, thanks!

Closing invalid as the cause appears to have been local file corruption.
