From mine (toshiba, but I believe the hp has similar graphic hardware):

dmesg:

[drm] Found VCE firmware/feedback version 40.2.2 / 15!

# lspci | grep VGA 00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Mullins [Radeon R3 Graphics]

I looked up that 'VCE firmware/feedback' line where it comes from in the kernel code. It seems that Mullins support in new to kernel 3.15.x (?) and still being actively worked on. Is that correct?

This is a different chip than Álvaro, so it's probably a different issue.
