Bug#931564: Kernel Won't Load Firmware?
Package: linux
Version: 4.19.37-5
The version: Debian 10 Buster
The hardware:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] RV610/M74 [Mobility Radeon HD 2400 XT]
On boot I see this message. In past Debian versions I can either
install firmware-amd-graphics to silence the message or ignore it;
either way the display would work fine.

With Buster things seem to fall over and die:

I decide to try to see if the firmware makes a difference. I enable
nonfree, install firmware-amd-graphics, and reboot but nothing has
changed. The exact same messages as above still appears; below. It's
almost like the kernel still couldn't find it, even after it had been
installed. I compiled a kernel from upstream which was able to load the
firmware and get a graphical interface. Since replacing the kernel
solved it I'm reporting this against the kernel.
