I think this is related to
If I am right, this is a conflict of i915 probing things before the backlight pwm driver
is ready. I might be totally wrong, though.
The current ubuntu image is working, I think they delay i915 till things are ready at the
expense of some garbled output at the beginning of startup.
The right place to fix this would be in the driver, but this didnt happen for some time.
A workaround would be to delay i915 in the initramfs.
I did try to start with rd.driver.blacklist=i915. This did NOT work for me.
This prevents installing arch with the iso.
This task depends upon

Reason for closing:  Not a bug
Additional comments about closing:  Nothing to do here. Please use forums to support request. Anyways, rd.driver.blacklist is for Dracut (Fedora/CentOS). Use nomodeset instead.
