Running userland should never result in crashing the kernel except if programs directly touch I/O hardware an do stupid things or abuse their root priviledges.. This type of crash specifically has in the past been produced by incorrect hazard barriers but also CPU hardware bugs so you may want to review the kernel code against a CPU datasheet and errata documentation. As always with hardware that is only supported out of tree we can't be too helpful ... Ralf
