[SB2] 4.16.x not loading properly

[versipellis]

I'm having this issue 90% of the time with kernel versions 4.16.x. 4.15.16 was my last working version with 100% success rate. Upon selecting the kernel, I get the Ubuntu loading screen with the five progress dots below it, there's the audio hiss sound.. and the screen goes to black. Keyboard lights up, and I have to hard reset. Occasionally, I'll get to the login page, type in my credentials, and have it go to black. Other times, I'll boot in fine, and then it'll go to black the moment I open up something.

I tried removing all previous kernel versions, /lib/firmware/intel/ipts, /lib/firmware/i915, /lib/firmware/nvidia/gp108, and /lib/firmware/mrvl before running the sudo setup.sh and sudo dpkg -i commands. I'm guessing it's probably a display firmware issue somewhere, but can't figure out what. Been happening on Ubuntu 17.10 and now 18.04, both Wayland and xorg.

run dmesg, its intel_power_well_enable error, exact same symptoms as on my sb2:-)

[versipellis]

Thanks @calidor, I'll take a look later tonight. I don't seem to recall seeing intel_power_well_enable, but maybe now that I know what to look for I might spot it :)

[calidor]

oh and thanks for hint, ill try 4.15.16..

[versipellis]

So, I get the same output as in your dmesg in #173, even for 4.15.16. It loads fine, however. I get the same for 4.16.7 when it loads properly. and when it doesn't load properly.

[calidor]

yeah, i had to stop using it becouse after boot windows shows thermometer on boot. sb2 is not hot.. and well my guess error hes something to do with power management .. and for me its dangerous, i dont want to brick this expensive machine:)

@versipellis which device?

[calidor]

ill look tomorow at this: https://gist.github.com/Brainiarc7/aa43570f512906e882ad6cdd835efe57

[versipellis]

@npjohnson SB2. Sorry, forgot to mention.

[calidor]

I am unable to reliably reproduce this``` I've had a 90% success rate for booting into 4.16.x this entire morning, and then this afternoon it started tanking again. I suspected that it might be due to external devices (USB, surface dock) but when I tried testing with it, it doesn't seem to improve success rates noticeably (I am suspecting mental bias in my observations)

dmesg from a failed boot has this, which is exactly as #173 - will close this issue as duplicate.

This is fixed in the 4.17.x series, which will upload here shortly.

Ah, got it, my apologies!
