Bug ID: 209417
Summary: kernel-5.8*, amdgpu - Blank screen shortly after boot,
"fixed" with suspend and wake up
Product: Drivers
Version: 2.5
Kernel Version: >=5.8
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: juantxorena@gmail.com
Regression: No

boot log 5.8.11 fedora
When using a 5.8.* kernel, the following happens:
- During boot, some initial messages appear, then the screen flickers a couple
of times and it goes blank
- I blind-enter the LUKS password, and it appears to work because
- pressing the sleep key of the keyboard (laptop) works and the laptop suspends
- after waking it up, it works normally
This happens with the normal boot options and without options "rhgb" and
"quiet". The problem goes away when using the "nomodeset" option in the kernel.
Hardware: Dell Precision 7530 laptop, Radeon Pro WX 4150 and integrated GPU
Intel UHD Graphics 630.
I have tried this with fedora kernels (the distro I use), and also with an
OpenSUSE live USB with a kernel 5.8.10. The problem persists, and the "fix" is
the same.
I attach the kernel log of a boot with the 5.8.11 kernel.
Extra information: I have had some problems with suspend, after suspending the
screen is blank and I have to close the lid and open again. This happens since
various kernels ago, but I never reported because it wasn't serious and I use
hibernate anyway. It may be related, since it works after suspend-wake up.

boot log 5.7.17 fedora - working
This is the boot log of a boot with the kernel 5.7.17 with fedora, which
doesn't present this problem.

Can you bisect?

> Can you bisect?
I never did it but I'm happy to help. It will take a while for me to do it,
though. Any guidance would be appreciated.
I assume that I will start with the first vanilla version that presented this
problem, right?

yeah, if it was working with 5.7.0 and not working with 5.8.0, you can just do
a bit bisect on
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/ between the
v5.7 and v5.8 tags. Google for "kernel git bisect howto".

bad-commit
I finally get to do the bisect. I attach the result of the guilty commit. I
wrongly assumed that it was a problem of amdgpu, but apparently is related to
the intel i915 drivers. I guess I should move this bug to the proper place.
