--- Comment #7 from Michel Dänzer michel@daenzer.net --- I suspect Alex meant the full dmesg output without nomodeset. :)

--- Comment #8 from hansmatros76@gmail.com --- Thanks but how can a do this?
Without this option in Grub i only see 1 second a few lines, then the monitor switch into a black screen. nothing happens anymore. also am not able to ping the host. i have to press the power button for a few seconds to force a shutdown.

Thanks but how can a do this?
You attached a partial dmesg output in comment 0. Can you just remove the grep so we get the full output?

--- Comment #10 from Alex Deucher alexdeucher@gmail.com --- Is this a regression? Did it work previously? If so, with what kernel?
