    Cannot boot on fedora 28 after kernel update

    Hi guys,

    Ever since fedora rolled out kernel version 4.17 i could not boot anymore.
    At first i was able to boot by selecting the 4.16 kernel but after updating the system again i can't even get to the grub, all i see is a black screen.
    I'm using a radeon R9 380 video card which it seems that only works properly in windows. I tried multiple distros and so far fedora was the only one which could handle it (never had any problem until 4.17 release). Is anything i can do except changing the video card or running linux in a virtual machine from windows ?

    can you boot from a Live USB stick ?
    if so, mount your / partition into /mnt , and modify the /mnt/boot/grub2/grub.cfg manually, and where it says set timeout=5 (2 locations)
    change to set timeout=30
    then try to reboot and see if it actually goes into grub.
    if you are able to, and boot into 4.16 , then I guess it's time to add some special Radeon configs into /etc/default/grub , but I don't know them cuz I am an NVIDIA guy.
