Used this script to do the initial install based off of s34n guide.

It worked and then the drivers unloaded and wont reload with the error: ERROR: could not insert 'piuio': Exec format error

Running Ubuntu 18.04 LTS, fresh install

`cd /home/mike/piuio/mod make clean make make install find /lib/modules -name 'piuio*' modinfo piuio depmod modinfo piuio modprobe piuio lsmod | grep piuio

salt '' kmod.check_available piuio salt '' kmod.load piuio ` ... with this output

I don't see the "make clean" step in the output. It looks like a module that you had previously built (with kernel 5.0.0-23, before your kernel was upgraded to 5.0.0-25) got reused in the install step. Since it was built against a different version, the current kernel correctly refused to load it.
