            Bug ID: 216806
           Summary: [Raven Ridge] console disappears after framebuffer
                    device loads
           Product: Drivers
           Version: 2.5
    Kernel Version: 6.0.8
          Hardware: AMD
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: vinibali1@gmail.com
        Regression: No

dmesg - debug drm, no dc

I have an HP c645 Chromebook with Ryzen 3 3250C APU.
Everytime, when the FB/DRM loads and vgaconsole get's deactivated, the console
freezes. I tried many common kernel parameters so far with no luck.
By default it freezes back in the boot sequence,
using amdgpu.dc=0 it freezes after the tty shows the login text.
I attached the logs with debug drm flags, with disabling the Display Core
driver, the last message is some BT device load message and right after that I
found the DRM load.

please make sure CONFIG_DRM_FBDEV_EMULATION is set in your kernel config.

Hello Alex,
it's set:
$ zgrep DRM_FBDEV /proc/config.gz 
CONFIG_DRM_FBDEV_EMULATION=y
CONFIG_DRM_FBDEV_OVERALLOC=100
I just got a hint to use the iommu=pt, but that one didn't work too.

Just some more information to share here. I gave it another try, and the
console  freezes exactly at the moment when drm enables the kernel modesetting. 
[    6.329371] [drm] amdgpu kernel modesetting enabled.
With nomodesetting it works like it should, the vgaconsole remain active and
useable.
Do we know somebody who has some knowledge to understand the DRM logs?
Otherwise these lines are pretty strange for me:

The latest 6.5.5-arch1-1 kernel just turned the display into a full white
screen with high brightness.

It turned out with the latest kernel the amd_iommu=off did the trick.
