I am currently stuck on kernel-4.8.16-300.fc25.x86_64. Any 4.9 kernel I try to use wont let my PC boot. As soon as i hit enter in the boot menu, the Fans in my PC spin up to 100% and video signal seems to disappear because my monitors go into sleep mode.

This is a new account so I cant attach lspci output or journalctl -b or journalctl -k output. I guess i could paste that info in here is anything thinks it may be helpful. I tried checking /var/boot.log but it is empty for some reason

Any help would be appreciated.

Thanks, Matt

you can always paste outputs of the above commands to fpaste.org and then link them here.

Catch boot, hit E, add nomodset to Linux cmdline and hit Ctrl-x, see if it lets you boot in vga graphics mode. What desktop are you running? if you do get in then see if it needs an update, and also check status of the video driver, make sure it updated with the kernel.

I have uploaded the output of journalctl --since today. I have only booted 2 times. Once attempting kernel 4.9.6 and once with a kernel that boots 4.8. I have also included the out put of lspci. I will try steveebey's reccomendation and post the results

journalctl today : https://da.gd/LTvnP

lspci : https://da.gd/W18Si

@steveebey73742 I tried adding the nomodset and as soon as I hit Control - x the fans spin up 100% and I dont get any video.

I am using the stock desktop gnome 3. Processor is a Xeon 4 core with 32 gigs of ram, Multiple ssd's, etc... I'd love to figure out whats going on with the newer kernels

Also here is more of the journalctl output since fpaste is limited on how much i can paste. This contains the end of the 4.9.6 boot where it just stops https://da.gd/EbNK

Are the video card drivers set to update with kernel upgrades? I use nvidia and have the dkms setup to rebuild them when I get new kernels? set runlevel to 3 and reboot. see if you get a login. then try reinstalling the dirvers, so they rebuild to the current kernel.
