journalctl --no-hostname -k > dmesg.txt

1. Please describe the problem:

Acer Nitro 5, AN515-42 , Fresh Fedora 29 install with all updates applied.

To install (otherwise Fedora Live CD fails to boot with CPU#n Stuck messages) the following kernel parameters are added at live cd grub screen:
  rcu_nocbs=0-7 ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 

After a successful installation, at boot time, there is a 70% chance that the machine will hang with a dark screen. The machine starts up, GRUB appears, after selection a few pages of information appears and then the screen goes dark.
At this time no ALT-Fn keys will function, and the machine will be unresponsive.   Only a power off, and power on will recover the machine.

The other 30% of the time the machine powers up fine and GDM and then Gnome appears as normal.

2. What is the Version-Release number of the kernel:

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at :

No -- the machine was formatted today, but before then Fedora 29 was also installed, and the SAME problem was present -- with the older 4.x kernels.

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

Just turning on the machine, wait and it will most likely happen.

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:
I am unable to try it.

6. Are you running any modules that not shipped with directly Fedora's kernel?:

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.

I'm very happy to report that the problem seems to have gone away..
Perhaps the latest BIOS update fixed it.
