Comment 7 for bug 1927808

I tried 5.13, installing packages
  linux-headers-5.13.0-051300rc1-generic_5.13.0-051300rc1.202105092230_amd64.deb
  linux-headers-5.13.0-051300rc1_5.13.0-051300rc1.202105092230_all.deb
  linux-image-unsigned-5.13.0-051300rc1-generic_5.13.0-051300rc1.202105092230_amd64.deb
  linux-modules-5.13.0-051300rc1-generic_5.13.0-051300rc1.202105092230_amd64.deb
Booting 5.13, the graphical (GDM?) login screen did not show; there was a mouse
pointer (moving correctly with the mouse) but otherwise black screen.
I could log in to the TTY console with Alt-Ctrl-F2, and obtained the output of
dmesg as attached; I wonder about the
  Initramfs unpacking failed: Decoding failed
line within.
Without the graphical login, I did not think I could properly test the rtw88 module,
did not remove the line
  blacklist rtw88_8821ce
from the /etc/modprobe.d/blacklist.conf file.

Should I re-try 5.13, somehow differently?
