    Acer Nitro AN515-42 and its boot problem

    When I first installed Fedora 29 on my Acer Nitro 5 laptop, it was not a happy machine. Eventually I was able to get it working after much head scratching.
    Via trial and error these kernel parameters seem to work:
    GRUB_CMDLINE_LINUX="resume=UUID=5d1e3899-cc67-4b39-8e26-633f1ce044c9 rcu_nocbs=0-7 ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 pti=off"
    If I launch the system with the default kernel parameters it gets stuck with CPU#2 Stuck for 23 seconds message.

    Things went OK until I decided to install Virtualbox. I used the Virtualbox from the virtualbox web site..
    That installer caused some major problems, and gdm would no longer display a login screen.
    So, from a command line I installed and enabled sddm display manager instead.

    That allowed me to boot. However it only works about 1/3 of the time. The other two times, I get a dark screen, no way to switch to anything, cannot be ssh'ed to, thus in essence the machine is dead. About every third time, the machine boots up fine and I get the display working.

    At shutdown, similar scenario -- the machine does not shut down. Dark screen, power still on.
    I hold the power button 5 seconds to turn it off.

    Any ideas what to do?

    I'll include lshw so you can see what the hardware is.

    I'd remove the installed virtualbox you obtained from their website and instead use it from rpmfusion repositories as the rpmfusion builds are compiled specifically to deal with fedora's foibles.
