I would prefer 4.11.0 as it supports most of the mainboards newer ACL
sound codecs:

linux-4.11.0_ryzen01_amd64_generic.tar.gz

As I can tell, Gigabyte is not really takling the issue because only a
very small number of people are affected by it. Alternate Operating
Systems are not worth investing time and money (you have to get someone
with good know how in Linux Development to fix this error). Thats just a
fact. If this was an Issue with ASUS or ASRock or whatever brand, we
wouldn't get any support either.

The only thing we can do is 
1) Install custom kernels or disable AMD_PINCTRL
2) Wait until AMD releases a fixed version of the Module; 
It seems like an Issue with a NULLPOINTER on some of the higher PINS, then the 
Kernel gets stuck in a infinite loop, trying to get the Module to load, instead 
of just skipping it. If we get a release where the error is handled and loading 
of the module is fixed (by ignoring / aborting it), we can use Linux under 
Gigabyte Mainboards just fine.

But how do we get it fixed? Who is the maintainer of the Module? AMD
itself? I dont really know.

Title:
  System doesn't boot properly on Gigabyte AM4 motherboards (AMD Ryzen)

Status in Linux:
  Unknown
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I'm trying to run ubuntu on Ryzen 1700x with Gigabyte GA-AB350-gaming-3 
motherboard,
  and it has a load of problems, starting with not being able to boot normally.

  During normal boot, on 16.10 as well as 17.04 beta:
  system doesn't boot normally, hangs with a lot of "unexpected irq trap at 
vector 07"
  messages displayed.

  
  Following advice from various places, I've tried:disable cpu freq governor 
and cpu handling in acpi settings

  1. add "acpi=off" to boot params

  That helps, allowing me to boot into recovery mode, though it leaves
  me with system seeing only one core, is really slow and still only
  boots in recovery mode.

  2. Compile own kernel using 4.11.rc1 and disabling cpu freq governor
  and cpu handling in acpi settings. Boot with "quiet loglevel=3"
  option.

  That gets me even further - system sees all cores now. Still only recovery 
mode though,
  but its enough to get info for this bug report.

  Some observed problems:

  1. dmesg reports *a lot* of messages like this all the time:

  [  163.362068] ->handle_irq():  ffffffff87a7e090, 
  [  163.362081] bad_chained_irq+0x0/0x40
  [  163.362089] ->handle_irq():  ffffffff87a7e090, 
  [  163.362090] amd_gpio_irq_handler+0x0/0x200
  [  163.362090] ->irq_data.chip(): ffffffff88587e20, 
  [  163.362090] ioapic_ir_chip+0x0/0x120
  [  163.362090] ->action(): ffffffff884601c0
  [  163.362091]    IRQ_NOPROBE set
  [  163.362099] ->handle_irq():  ffffffff87a7e090, 
  [  163.362099] amd_gpio_irq_handler+0x0/0x200
  [  163.362100] ->irq_data.chip(): ffffffff88587e20, 
  [  163.362100] ioapic_ir_chip+0x0/0x120
  [  163.362101] ->action(): ffffffff884601c0

  I've tried to redirect dmesg to a file, stopped after a short while,
  it generated 400M of those.

  2. Systemd cannot start journald. Perhaps because it cannot cope with
  amount of kernel logs?

  3. Looking at pci, I've noticed something called AMDI0040
  (/sys/bus/acpi/devices/AMDI0040, path=_SB_.EMMC), among AMDI0010,
  AMDI0020, AMDI0030. Those however are mentioned in kernel source,
  kernel and google are completely silent about AMDI0040.

  
  Phoronix tested ryzen using different motherboard, and it worked better 
(though not well),
  so I suspect it is an issue with motherboard.
