That's a bug I fixed, but it didn’t make it into the 4.8 branch until
4.8.10[1]. Unfortunately that’s not yet been packaged for Debian. There
is 4.9~rc5-1~exp1 in experimental, but I haven’t tried that build, and I
don’t know if the serious regression of not being able to load kernel
modules has been fixed. My suggestion would be to try the experimental
package, but that may fail with a whole load of missing memcpy etc
symbols, in which case I recommend compiling an upstream version from
the 4.8 branch (currently 4.8.11[2] is the latest stable release).
Regards,
James
