Bug#900087: AMD RX 550 often locks up

["Simon Iremonger (debian)" <debian@iremonger.me.uk>]

I would generally say this looks like problems more in kernel
and firmware land, than bugs in the xserver driver to me...

I would, generally note a lot of wider AMD instability/issues
(that Alan) talks about improved a lot in 5.8-ubuntu
and 5.10-debian (bullseye and buster-backports) kernels.
Even 5.4-ubuntu kernels still have problem with some newer
Ryzen systems.

In short, I'd recommend testing debian buster-backports
version of linux-image-amd64 linux-headers-amd64 and
report back on this bug.  In particular -- can this
bug now be closed, anyhow?  How could debian warn
users to update BIOS/firmware?
