--- Comment #5 from Steven A. Falco <stevenfalco at gmail.com> ---
I began having problems with my AMD GPU when Fedora 25 switched from their
4.8.16-300.fc25 kernel to a 4.9.3 kernel, as described here:

https://bugzilla.redhat.com/show_bug.cgi?id=1414025

The initial symptom was that there was no kernel frame buffer, so the system
dropped back to using an accelerated video interface.

With the latest Fedora kernel (4.9.6-200.fc25), the system eventually runs
normally, but it takes upwards of 6 minutes for the system to boot.  As shown
in the files I attached, I too get many messages of the form:

[  346.235933] 
                failed to send pre message 148 ret is 0 
[  346.455587] 
                failed to send message 148 ret is 0 

I'd like the importance of this bug raised to medium or high, as it is a clear
regression from the 4.8.16 kernel to the 4.9.3 kernel.
