Well, I can reproduce the problem just with the option
acpi_backlight=vendor which is needed if i want to toggle brightness
When I reported the problem I have been advised to create a bug
report to make sure the "possible quirks made to make work the
brightness" are integrated upstream, so that we can then refocus on
the sleep/resume crash
so the timeline is:
- - I report the crash/resume bug and get redirected to creating a
video bug instead
- - I report the video bug and get redirected to sending the
information to involved people/dev because it's an upstream bug
- - I report the problem here and I'm advised to use
"acpi_backlight=vendor" to fix the problem
so I'm a bit confused about what I should do now :-)
