So all we can say, is that one of the “partition readers” in (gnu build
file-systems) hangs while reading from one of these.

I don’t have good advice other than trying to run the code by hand to
find out which device/reader pair causes the problem.

I hope that makes sense.  We can further debug this on IRC if you want.

Thanks,
Ludo’.
