--- Comment #1 from feh@fehcom.de ---
I've got serveral crashes how. I all cases it points to the same problem:

As a reminder: https://wiki.freebsd.org/LinuxKPI

Not very satisfying. Any hints, which programs produce this behavior? How c=
an I
tell, which programs require the Linux compat layer?

--eh.
