Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

	When I upgreeaded from kernel 5.6 to 5.7 a long time ago, my system broke.
	I first saw some firmware errors when booting.
	But when I fixed those firmware errors by adding non-free and contrib repos,
	and installing firmware-linux,
	those errors disapeared.
	Now it simply goes black at some point during the boot.
	If I boot with linux 5.6, however, everything runs fine.


   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   * What was the outcome of this action?
   * What outcome did you expect instead?

	Ineffective: Upgrading the kernel to 5.8, or 5.9.
		None of the kernels >= 5.7 work.

	Worked: Run with kernel 5.6 (or older).

	Ineffective: Clean install from DI-alpha2.
		This provides two kernels: 5.4 (works) and 5.9 (doesn't work).

	I also tried installing firmware directly from kernel.org:
		git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
		sudo make install
	but it didn't fix it.

You can find the Debian changelog in
/usr/share/doc/linux-image-5.9.0-4-amd64/changelog.gz .

Mostly apart what you will see on Debian changes it will list mostly
(a filtered changelog as well from the repsective upstrema changes
from the stable version imports).

Regards,
Salvatore
