I have been trying to get Fedora 21 running on my desktop for the past week, but I have been running into all kinds of issues with kmod-nvidia and my graphics card. Whenever I try booting into System Upgrade in GRUB (created by fedup), I instantly receive a black screen and I am forced to reboot.

I was on #fedora IRC and I was given the advice to remove the kmod-nvidia packages via YUM, upgrade, and then reinstall. I tried doing that with no success. After booting back into Fedora 20, I reinstalled the drivers, reexecuted fedup, and tried rebooting for good measure.

After getting the same results as before, I restarted my computer to see only the few kernel options present in GRUB - none of the System Upgrade options like before.

Immediately upon choosing any of the available kernels, I am greeted with this message. (I apologize for quality but I am working off my phone right now.)

Kernel Panic!

Any help is greatly appreciated as I'm virtually without a system.

Edit #1

On #fedora IRC, I was told to install simple-storage-manager and provide its output, which I have done so here.

How did you remove the kmod-nvidia packages? Once you removed them, did you reboot into the same kernel to make sure things were working right?

@sideburns: I removed the kmod-nvidia packages via YUM. Once I removed them, I rebooted into the System Upgrade with no success. Then I successfully rebooted into the old kernel version and it did load successfully.

@baoboa: It is a newer card. It's a GTX 660 Ti.

There's probably some nvidia stuff still active. If you can boot to a CLI, try this, as root: yum remove \*nvidia\* as that will get rid of all of it.

look at fro debuging

add systemd.log_level=debug in the kernel boot option ( edit one entry at grub menu level)

Adding that boot parameter to the kernel made no change in the information that is displayed during boot. Any other ideas?
