Hello.  I have a crash dump for:

$ uname -a
Linux freedom 5.10.0-rc6 #1 SMP Sun Nov 29 17:26:13 MST 2020 x86_64 
x86_64 x86_64 GNU/Linux

Occasionally when this dumps it likes to lock up the computer, but I 
caught it this time.

Also video likes to flicker a lot.   Nouveau has been iffy since kernel 
5.8.0.

This isn't the only dump, it dumped probably 50 times.  If you are 
really desperate for all of it,

reply to me directly as I'm not on the mailing list.  Here is one of them.
