Thanks for your quick response. 

For installing 5.19.11-1 to confirm it works: When a package is not
anymore in the archive, you can use the snapshots service which
contains the old versions:

https://snapshot.debian.org/

You can get from there the old binary package which you can install:
https://snapshot.debian.org/package/linux/ (to get the unsigned
packages), or https://snapshot.debian.org/package/linux-signed-amd64/
for the signed one.

You can use the same as well for installing the newer versions (or
alternatively add, temporarily, the experimental and unstable
sources.list entries and install the packages).

For testing newer versions, 6.1.4-1 was uploaded earlier today to
unstable.

Knowing first if it's a regression from the linux packages would be
helpful, so confirming it indeed still works with 5.19.11-1.

Does this gives you some hints on how to start?

Regards,
Salvatore
