"If it's loaded then I guess it's..." <- Actually it is, I found that this message comes from the pd_mapper module: `PDM: no support for the platform, userspace daemon might be required.` The johan `6.11.0-rc1` kernel I am using indeed doesn't have support for the x1e80100. Is there perhaps a patch for it already somewhere, or do I have to try my luck with compiling the userspace driver?
