put
chunk-size 8
here and redo mkraid (possibly with -f).
It seems that the kernel is checking chunk size always, while raidtools are
checking chunk size for raid0,1,4,5 only.
IMHO kernel should not check chunk size for other raid levels, but if Ingo
thinks it should, then raidtools should either error on not specified
chunk-size for other levels as well or supply some default which will not
trigger the md.c MD_BUG().
Cheers,
