Today, I took my inspiron laptop for some gaming and found out the internal bluetooth was not present. I did some research in the system and the dmesg result was this. Has anyone found this same issue? Funny thing is bluetooth was working fine. I followed the directions given in PopOS troubleshooting site to solve the issue but no luck there:
