Bug#974166: 5.9.0-1-amd64 (5.9.11-1) has fixed the issue

["Alejandro Colomar (man-pages)" <alx.manpages@gmail.com>]

Hi,

I'm glad to say that just now I upgraded to the unstable kernel:

$ sudo apt-get install linux-image-amd64

and now I can boot normally:

$ uname -a
Linux debian 5.9.0-4-amd64 #1 SMP Debian 5.9.11-1 (2020-11-27) x86_64
GNU/Linux

I'm curious: I'd like to see the changelog and the code
to see what fixed the issue.
Could you point me to it,
or give me some hint so that I can search for it myself?

Thanks,

Alex
