Comment (by johkra):
I've tried hrev53183. When booting from USB with default options, I get a
black screen with working backlight. This is repeatable.
Enabling serial debug output is enough for Haiku to start with graphical
output. Any future boots after enabling serial debug output once also
start with working graphical output even if no boot options are changed. I
did not change any other debug options like safe mode.
Re-creating the USB stick leads first to a black screen and than to
working boot after enabling serial debug and changing no other options.
I'll provide serial logs after I can get hold of a working cable. If there
are any logs I can generate from the running Haiku system, please point me
towards instructions on how to do this.
(The integrated touchpad/trackpoint and keyboard don't work. An external
USB mouse works.)
