Using Thinkpad T495s with Ryzen 3500U, on Ubuntu Budgie 18.04.

After upgrading to Kernel 5.3, I ran into black screen at login and
general system instability, and lots of "failed to write reg ... wait
reg ..." in dmesg. No issues when booting to Kernel 5.0.

Seems like there are several amdgpu firmeware upgrades in the past few
week (https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git/log/). Followed these instructions (source:
https://www.phoronix.com/scan.php?page=news_item&px=Ubuntu-19.10-Radeon-
RX-5700):

git clone 
git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
cd linux-firmware/
sudo cp -va amdgpu/ /lib/firmware/
sudo update-initramfs -u
reboot

After that, and I'm no longer seeing "failed to write reg ... wait reg
..." in dmesg, and system is generally more stable.

Title:
  Kernel 5.2.3 fails to fully boot on Lenovo 330s-15arr, black screen at
  login screen with cursor

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Was on 4.20, booted fine (with the boot option
  ivrs_ioapic[32]=00:14.0)

  Tried to boot 5.2.3 (but I believe this happened on 5.1.X too)

  It will boot to a certain extent, it does my disk password, i can see
  everything say "ok" when i do no quiet splash. But where it should go
  to the login screen I just see a single cursor

  Setting nomodeset lets me boot, looking at logs:

  Seems maybe something to do with "failed to write reg 1a6f4 wait reg 1a706" 
but unsure how to fix it
