Comment # 3 on bug 1087261 from Takashi Iwai

Could you give the output of "rpm -q kernel-default" and "rpm -q
drm-kmp-default" ?

It might be that drm-kmp-default was used only in a newer kernel (or
vice-versa).
Usually KMP can be kept, but in the case of recent kernel update, it's
refreshed and becomes incompatible due to Spectre/Meltdown fixes.

In anyway, please give the hardware details, too.  At least, hwinfo output
would be helpful.
