Description lejeczek 2016-07-10 12:20:16 UTC
Description of problem:

4.7.x would not boot no matter what. Blank screen, nothing even with "verbose"
4.6.x weirdly using "verbose" as param would boot ok, sometimes would look a bit random.
4.5.x boots fine every time

please feel free to request more info.
many thanks

gee, it really looks random too me. I thought "verbose" helps for it forces display but I just had 4.7.x booted Ok as normal "quiet".
There is also "crackling" sound at one point during the bootup, as if audio subsystem was initialized or something.
Gee, is this Intel's 6th Gen really so bad?

Comment 3 lejeczek 2016-07-30 09:06:09 UTC
"verbose" really does something to boot, without it 99.9% chances it won't boot.
But that whole Dell e7470 is a quite a disaster:
- sometimes screen would flick and system is "done", only hard-cold-button power off "works".
- drivers for touchpad: xinput does not show "PS/2 Generic Mouse" and this why I think there is no scrolling with middle button and point-stick in Gnome.
- speakers would produce a crackling noise(although sound is OK) for a second, most of the times at boot, logon, resume and sometime when an multimedia app starts
- Fn Keys work in a funky way, eg. Display brightness works without pressing Fn.

I know this is not the place but in case anybody is contemplating buying this Laptop - my view is: HP EliteBook 745 G3 with AMD A12-8800B (which I decided to move onto) is by miles better, from kernel+Fedora perspective.

Comment 4 lejeczek 2016-08-13 10:50:52 UTC
ok, 4.8 does some good magic, OS boots now, but other problems of which most annoying is lack of mouse emulation with middle button to scroll, remain.
