On Intel Tiger Lake with CET enabled kernel, I got [16711.463247] traps: gnome-session-c[151724] control protection ip:7fc6d2cbc540 sp:7ffd8b0846e8 ssp:7fc6d2f06fe0 error:3(endbranch) in libglapi.so.0.0.0[7fc6d2cba000+d000]
This bug appears to have been reported against 'rawhide' during the Fedora 33 development cycle. Changing version to 33.
Fixed as of mesa-20.2.6-1.
