Hi, the bug seems to be fixed by running "sudo update-initramfs -u" and correcting the BIOS configuration display setting from "Switchable Graphics" to "Discrete Graphics".
The PulseAudio Daemon message is gone and the radeon UMS message is gone. The background of this is i have blacklisted i915 Intel Integrated Graphics by blacklisting it using "install i915 /bin/true".
