Srijan Kumar Sharma, this report is only scoped to disk performance with
AMD Carrizo FCH Controller (not keyboard, wifi, booting, or any other
problem).
Hence, it will help immensely if you filed a new report with the Ubuntu
repository kernel (not mainline/upstream) via a terminal:

Srijan Kumar Sharma, to be honest I thought about making separate bug
reports but I think maybe Linux kernel is sponsored by Intel or
something. Because all my bug reports related to machines with AMD
processors got silently ignored after making me collect information

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
Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.8 kernel[0
The 4.8 kernels do not boot at all. I had very strange results. First it
gave errors about soft lockup. But the hardware is perfectly fine, I am
running windows and xenial (albeit slow) with no crashes or errors. Also
ran memtest and everything was fine.
The generic 4.8 is somewhat trying to boot

Meanwhile, I tried the amdgpu-pro drivers and they keep crashing one way
or another. It feels like somebody made sure that linux won't function
on this hardware.

It makes no difference whatsoever the difference is within reasonable
limits. Still much slower than windows host/ubuntu guest.

Evren Yurtesen, to keep this relevant to upstream, one would want to
test the latest mainline kernel (now 4.8-rc4) as it is released.
Could you please advise?

Amazingly the RC4 kernels booted! I tried both low latency and generic
and problem is still there.
It may be unrelated but I think it is worth mentioning never the less. I
have problems with keyboard skipping keypresses (Eg. forgets that I keep
my finger on CTRL key, does C instead of CTRL-C etc.)
In addition, I tried 14.04.4 with 4.2.0-27-generic, result is same.,.
