I am was using f40 by dual booting with windows and there was no issue. But after upgrading to f41, after some time the whole system hangs up and only the mouse can be moved. I tried deleting and installing a fresh f41 but i get the same result. There is no problem with f40.
This might be a known issue. Do you have an Nvidia GPU? If so, you could try this workaround (from a text console in case you can’t reach a graphical session).
It the above solution is not working, please post the output of inxi -Fzxx, and provide some details about the issue (e.g. at which point does it happen: before loggin in, when using specific apps etc).
