Description andré blais 2018-07-27 21:17:54 CEST 
It seems to boot normally to the point where it should display on screen, but screen remains blank.
Waited a few minutes.  (tried twice)

The previously installed kernel-desktop-4.14.50-2.mga6 continues to work normally.
Comment 1 Marja Van Waes 2018-07-27 22:30:44 CEST 
please reproduce the issue with the new kernel, then boot the old kernel and run, as root:

    journalctl -b-1 > newkernel.txt

and 

    journalctl -b > oldkernel.txt

and attach both files to this bug report

Created attachment 10295 [details]
journalctl log ; old kernel which works.

Note there are 3 error messages/warnings which display, but everything seems to work properly.

They may be due to using a usb key for important data.
It has 2 partions, both in fstab, mounted under my user account.
(It allows easy transfer to another computer if problems.)
Comment 4 andré blais 2018-07-28 04:48:13 CEST 
Let me know if you want the entire newkernel file.
It doesn't seem useful, since the video error messages seem to repeat a lot.

Is radeon-firmware installed ?

Comment 6 andré blais 2018-07-28 20:58:34 CEST 
It wasn't, but installing radeon-firmware didn't help.
Same symptoms.
The disk churns continuously without any display once selecting the kernel to start, long after the first display usually appears (in maybe 15 seconds).

The previous kernel still works nicely.  (with the same 3 error/warning msgs)

Before there were only 3 radeon packages installed
 (all required by other pkgs) :
lib64drm_radeon1-2.4.91-1.1.mga6.x86_64
libdrm_radeon1-2.4.91-1.1.mga6.i586
radeontool-1.6.3-7.mga6.x86_64
Comment 7 Thomas Backlund 2018-07-28 21:04:52 CEST 


You need to re-create the initrd after installing the radeon-firmware...

if you boot to 4.14.50-2, then as root in a terminal:

dracut -f /boot/initrd-4.14.56-desktop-1.mga6.img 4.14.56-desktop-1.mga6

and then you can try to boot into 4.14.56 again
Comment 8 andré blais 2018-07-29 22:05:06 CEST 
With recreated initrd, works like a charm.
(with the same 3 error/warning messages I had with previous kernels.)

Thanks Thomas !

Why didn't wasn'r radeon-firmware needed before ?
