backtrace trying drm-4.17
As stated in bug 105760, drm-4.17 didn't make any difference for me, though,
setting acpi_backlight=intel_backlight, as mentioned
in(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1656649), allowed me to
boot once without any backtraces, using an stable kernel:
$ DRI_PRIME=1 glxinfo
...
OpenGL vendor string: X.Org
OpenGL renderer string: AMD Radeon (TM) R7 M360 (ICELAND / DRM 3.23.0 /
4.15.12+, LLVM 6.0.0)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 18.0.0
OpenGL core profile shading language version string: 4.50
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
...
I'll try to reboot several times to see if the work around works always, and
let you know about it.
Thanks!
José.
