I compiled and installed version 1.3.2. I didn't verify if this version 
is actually working OK.
The tests run during the build for quite some time and I didn't observe 
an error, so I assumed
it ought to be fine.

OK, so the success of the zstd tests depend on the version of the 
library, not the version
of the kernel, right?

I can offer to send some output of the failing tests if it helps.

Thanks a lot + best regards, Uli
