Can you still reproduce the issue in buster with newest 4.19.y kernel?
Can you reproduce the issue with unstable's or buster-backports
kernel?

Not this issue, but I got other crashes since. The latest one:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=970557

i.e. with 5.8.10-1 in September 2020. I had no longer any issue
until the machine crashed again (I assume) in December, but
I don't have a physical access to it currently.

Control: tags -1 - fixed-upstream

Removing the fixed-upstream tags to avoid confusion since the bug
is still open upstream and I've never heard of any fix.

Yes, makes sense (the fixed-upstream came from the debian-bts-link).
