[coreboot] G505s with Coreboot unable to run any version of Qubes

Wed Dec 27 23:19:00 CET 2017

Hey, I'm having some heavy trouble getting my laptop to run Qubes and I first thought I was having issues with the OS. But after digging into the logs I managed to get(crashes too early during boot to get any persistent logs, had to write most by hand) it feels more like an issue with my Coreboot built.

So there are the details :
- G505s with integrated HD 8650G + discrete R5 M230 graphics.
- Coreboot 4.6-2477-g6ab3edac3c-dirty with processor microcode patch (change-ID: Ibbfee47ce1d5081640d6924e2b12f5213a7fcadb).
- Runs Debian Stretch fine.
- Fails to start Qubes 3.2 / 4.0 rc3 / Live 3.1.
- I added the vgabios.rom for the integrated card with menuconfig and the one for the discrete card with cbfstool.
- Coreboot.rom, .config and full make output as attachment.

Some more error data I gathered from coreinfo's Bootlog :

"..." are parts I didn't write down as they didn't show any obvious errors(but I'm bad at seeing them) and it would take me a loooong time to write down the full log as I can't export it as far as I know, if you need any more information from it, I can write down any part missing.

Output of "cbfstool coreboot.rom print" after I added the optionrom for the R5 M230 discrete graphic card :

What happened when I tried to boot each version of Qubes :

Live 3.1 :
mce: Unable to init device /dev/mcelog (rc: -16)
radeon 000:04:00:0: Invalid ROM contents

EXT4-fs error (device dm-0): ext4_find_entry:1289: inode #41642: comm plymouthd: reading directory lblock 0
(Hangs at the Qubes graphical loading screen, with loading bar full.)

3.2 (Install looked fine) :
Hangs at "Booting from Hard Disk..." in SeaBIOS on every try

4.0 rc3 :
[ FAILED ] Failed to start Load Kernel Modules.
...
[ OK ] Reached target Basic System.
(Hangs for about 10secs, followed by 5s of black screen)
BUG: Unable to handle NULL pointer dereference at (null)
(followed by a lot of output likely concerning the error and quickly back to boot)
Sadly too much output and disappearing too fast for me to get anything out of it if all I can do is read and type to export it. Tried Ctrl+S/Ctrl+Q to "pause" it but nope, also checked that the laptop should not reboot in case of kernel panic but it still does...

Thanks to anyone that could help me find what's wrong and how to fix it :)
