Then we may update the results table to: Kernel 4.9.130 4.18.20 4.19.12 4.19.16 ------ ------- ------- ------- ------- vlc-3.0.3 okay okay program_hangs okay vlc-3.0.6 okay okay program_hangs okay The tested kernels are: package-version kernel-version --------------- -------------- linux-image-4.9.0-8-686-pae 4.9.130-2 linux-image-4.18.0-0.bpo.3-686-pae 4.18.20-2~bpo9+1 linux-image-4.19.0-0.bpo.1-686-pae 4.19.12-1~bpo9+1 linux-image-4.19.0-0.bpo.2-686-pae 4.19.16-1~bpo9+1These packages are referenced by a meta-package linux-image-686-pae, which still has a different numbering scheme.
I don't know, what caused the problems with vlc, or what solved them in the end. I suspected at some point, that there might be changes to the "radeon" driver, but there are no obvious changes to "radeon" between kernel 4.19.12 and 4.19.16. So it might be a side effect of something completely different.
I learned, that old package versions can be found at https://snapshot.debian.org/ , if others like to repeat these tests.
