If you wish to change the kernel version, replace the url in the script with the kernel you want to use. the script will leave you in the download directory. just run the commands there
You might get this error
make: *** [Makefile:1083: certs] Error 2
Open the .config file with nano
and comment these 3 options
CONFIG_MODULE_SIG_KEY="certs/signing_key.pem" CONFIG_SYSTEM_TRUSTED_KEYRING=y CONFIG_SYSTEM_TRUSTED_KEYS="certs/rhel.pem"
save and exit
Getting the following:
[[email protected] Downloads]$ make localconfig
make: *** No rule to make target 'localconfig'. Stop.
Does it matter that I am on Fedora 30 right now? Don’t mean to keep jumping, was trying different things to see what would work.
try make localmodconfig
[[email protected] Downloads]$ make localmodconfig
make: *** No rule to make target 'localmodconfig'. Stop.
I guess needs to be CentOS.
Alright leave this with me and ill see if i can get you a patched fedora kernel
Thank you very much. I’ll keep this with Fedora 30 without modification.
I could also try CentOS since this is a new build and I’m trying stuff. Should I go for it and use CentOS 7 or CentOS 8?
I was using CentOS 8 for the testing, but shouldn’t be too hard to get a patched kernel. How come you aren’t going for something like Ubuntu for passthrough
Not sure. I am switching over from Windows and fell into RPM Distros so I am more comfortable with the package mangers. I was planning to use this for plex, vms, some gaming and ZFS but not sure if the distro makes a difference for the ZFS part. That said, I was able to setup passthrough on Debian 9 but that is on an Intel platform and I can’t really start pocking at that one too much because that is my main system for now. I am running Windows on it for the most part and trying to switch over but the road has been a bit tough because I would like to do the mentioned pass-through plus I am looking for a PDF solution where I would be able to do OCR as easy as Adobe Acrobat.

Tried this on a fresh CentOS 8 install on another machine.
[[email protected] linux-5.3.1]$ make localconfig
make: *** No rule to make target ‘localconfig’. Stop.
make: *** [Makefile:562: localconfig] Error 2
Then commented out the lines.
make localmodconfig produced a bunch of questions that I just “ENTERED” through.
make rpm-pkg from
eventually produced 3 rpms in
Is it now a matter of installing all 3?

install all 3 and update grub then reboot and see if its fixed
Installing kernel-5.3.1-1.x86_64.rpm and kernel-devel-5.3.1-1.x86_64.rpm succeeded but kernel-headers-5.3.1-1.x86_64.rpm failed with
error: Failed dependencies:
kernel-headers is obsoleted by kernel-headers-5.3.1-1.x86_64, so I am not sure what that means; is it because it is already installed?
Regardless, I updated grub and now am able to boot into 5.3.1 so have to try it on my other system that has dual GPUs.
Question, is there a way to see that the patch made in?
Gotcha, thanks a lot! I will try this when I get to my other system. However, does this mean that this sort of process will need to be followed for every kernel update?
Well yes, if you want to update the kernel you will need to download and recompile the kernel, this patch is not in the kernel
I think I figured out the kernel compilation part somewhat. Would you happen to know how to get a particular fedora kernel version? For example, I am current running
5.2.18-200.fc30.x86_64 which came in after
dnf update. Would you happen to know how I can get that particular version?
OK, so I think I’m getting the hang of compiling the kernel. Currently trying to compile the Fedora 30 kernel using fedpkg local.
I have 2 directories that keep growing in size. This is running in a vm with 1 core and it is taking hours and now the compilation failed because it ran out of space. I started with 24K and I had nothing else running. Does any one know why the directory sizes get so big?
