#65585 — Bug#944420: linux-image-5.3.0-1-amd64: green screen in X

Package: src:linux
Version: 5.3.7-1
Severity: important

A few days ago, I installed Debian on a new Ryzen 3400G system (not the system
on which I write this report, hope reportbug doesn't add any invalid
information from the system on which I type this).

I see graphical problems in X. I am not sure if the bug is in the kernel or
elsewhere, but the kernel seemed the most likely candidate for the bug report
to me.

I have installed XFCE. After boot, I see the graphical login screen. After
login, most of the time, the screen turns a dark green (so I don't get to see
XFCE). Sometimes I do get to XFCE, but then there is graphical corruption.

Despite the screen going green (which seems permanent - switching to a console
won't help), I can still switch to a console and type blindly. That way I
obtained the dmesg output I put at http://www.colecovision.eu/stuff/dmesg-log

I have also tried with kernel options ioomu=off and iommu=pt init=nomwait, but
neither one helped. The same system seems stable on Windows 10, so I guess it
is not a hardware issue.

Some installed packages:

linux-image-amd64 5.3.7-1
firmware-amd-graphics 20190717-2
xserver-xorg-vieo-amdgpu 19.1.0-1

#65586 — Bug#944420: Wrong info

I see reportbug added a lot of information from the system on which I
submitted the bug report. Please disregard that; sorry for the noise.

Do you need any further information from the system on which I see the
bug that I should provide?

#65587 — Bug#944420: Also tried 5.2.0

I also tried an older 5.2.0 kernel:

linux-image-5.2.0-3-amd64 5.2.17-1

The problem there is the same, but it seems I have a somewhat higher
chance to make it to XFCE (in which I still see graphical corruption)
than just getting a green screen (which I there see bit less than half
of the time).

#65688 — Bug#944420: Two more confirmations

Two more Manjaro users with of the green screen hang on XFCE start using
3400G with a 5.x kernel: One in the thread mentined above, the other in

#65706 — Bug#944420: Can't reproduce when using 5.1.21 from Ubuntu packages

Today, I've also installed a 5.1.21 kernel from Ubuntu on my Debian
GNU/Linux testing system, and logged into XFCE thrice. I did not see the
green screen crash with that kernel, though once I got a crash (system
frozen, only mouse pointer still moveable) a few minutes after logging in.

#65764 — Bug#944420: Bug confirmed with 5.x kernel on Manjaroo, too

Apparently someone has the same problem (AMD 3400G APU, mainboard with
B450 chipset, 5.x linux kernel, green screen crash just after login)
using a RC of linux 5.4 on Manjaro:

#66418 — Bug#944420: Fixed in 5.5

The green screen lockup issue is fixed in 5.5.

I've tried 5.5rc5 from experimental. While it crashes a lot and shows
graphical corruption in XFCE, I don't not get the green screen lockup.

I've also compiled 5.5.6 myself. With that kernel, crashes are a lot
less common (though they still happen in games sometimes) and the
graphical corruption is gone too.
