Hello everyone. I need some information on "Tainted Kernel". I used to know that using proprietary drivers causes a kernel to get tainted but I don't really understand the real meaning of "taint". Does using custom CPU scheduler and/or using tools like hdparm makes a kernel "Tainted"?

If your kernel dies often, you load akmods (or, much worse, virtualbox) use non-gpl drivers, if your kernel needs to use workarounds on your machine...

What is the Value of cat /proc/sys/kernel/tainted @HellBanger ?

What is the Value of cat /proc/sys/kernel/tainted @HellBanger ?

G W

You have used additional Modules.

Did you install vbox?

No

vanilla install

Any other gpl mods?

 cat /proc/sys/kernel/tainted 0

Linux tobias 4.14.13-300.fc27.x86_64

 cat /proc/sys/kernel/tainted 0

512

Oh

your kernel just has issued you some warnings

check dmesg for errors

Your specific pc may have some bugs linux needs to work around

^^ Got this in dmesg

amdgpu had troubles initialising, yes thats worth a warning.

lspci -vv

can you copypasta the gpu model and see if it uses radeon or amdgpu?

All right, so this should be fixed in kernel 4.15 with audio and general ridge patches coming.

If your pc boots fine for now and has graphics acceleration wait for 4.15 release

Okay. Thanks for the information. I will look forward to the 4.15 release??
