Boot freezes on newer versions of Linux
Hello, I have been having an issue where if I upgrade Linux past 4.7.5 the boot freezes at loading initial ramdisk. I have tried running "Mkinitcpio -p Linux" but that doesn't seem to help.
Adding early print the kernel parameters gave me this:

I believe this is something todo with the AMD Driver. I do notice the same error starting kernel 4.8

Re: Boot freezes on newer versions of Linux
Yes, but even with the new open source driver. All the dual graphics with APU has been having the same issue.
The only solution I have is to downgrade to 4.4. I dont mind since its LTS.
Based from your error your device is Toshiba S855D which has APU and discrete GPU.

Re: Boot freezes on newer versions of Linux
You cannot also boot on some intel based laptop. See this bug : https://bugs.archlinux.org/task/52246
Looks like linux 4.9.0 is kinda buggy 
By the way, the AMD bug is this one : https://bugs.archlinux.org/task/52227

https://bugzilla.kernel.org/show_bug.cgi?id=191121? You can check if it is the same issue by reverting the specified commit in the bug report or performing a bisection.
Edit:
8e80632fb23f021ce5a6957f2edcdae4645a7030 can not be cleanly reverted, from
https://git.kernel.org/cgit/linux/kerne … e4645a7030
its parent ( the previous commit as it only has a single parent) is 31ce8cc68180803aa481c0c1daac29d8eaceca9d
https://git.kernel.org/cgit/linux/kerne … d8eaceca9d
Checking out 31ce8cc68180803aa481c0c1daac29d8eaceca9d should produced a kernel that boots while applying 8e80632fb23f021ce5a6957f2edcdae4645a7030 should produced the bug.
Although a full bisection would still probably be preferred by upstream.
