     96        Kernel versions in the 4.1 and 4.2 series have a broken RAID
     97        implementation. If you want to use RAID type LV's, you should
     98        install a kernel with version above 4.2.4. Note that several
     99        tests use RAID logical volumes, and can generate a <quote>kernel
     100        oops</quote> with faulty kernel version, which ususally renders the
     101        system unusable.
