Hi,
My Model is 15-ab125ax
I Would like to report that I have same problem as OP (Disk speed,
keyboard, AMDGPU-Pro) and problem with wifi. Ubuntu 16.10 does not boot
("AMD-Vi: Completion loop timed out" followed by kernel panic). I had a
lot of phone and email conversations with HP support and it does seems
like my Laptop is locked for WINDOWS 10 ONLY. Currently I'm using Ubuntu
16.04 with self compiled 4.7 kernel from AMD staging which allows me to
install AMDGPU. I'll try 4.8-rc4.
Hope this is helpful to someone.
Regards
