Thanks for the advice.  I did a binary search through the kernels on snapshots 
and found that 4.10.0-trunk-amd64 (possibly the earliest one that's later than 
Stretch) had the problem too.

Now I'm on 5.0.0-trunk-amd64 which has been going fine for 5 days and probably 
has no problems in this regard (usually the problem occurs in 1-2 days but 
there's enough variation that it's not impossible I just got lucky).  I guess 
I can track Unstable for kernel releases on my laptop until Bullseye is 

As an aside, the Stretch kernel lacks the NNP SE Linux functionality that is 
in the Buster kernel which means that some daemons like mysqld run with 
elevated privileges.  I'll blog about this shortly.  The summary is that a 
Stretch kernel with Buster SE Linux userspace (particularly systemd) is an 
unsupported configuration.  It is not possible to get a SE Linux system with 
Buster systemd and Stretch kernel to work correctly.
