   For my self-compiled kernel, built-in. This actually seemed *very* 
common problem, see e.g.
   (the comments actually helped me a lot when I tried getting Gentoo 
installed and Intel RAID5 going).

   Comment 5

happens to mention that there's been a rename of the module - 
device-mapper/dmraid/something is expecting dm-raid45 but module is 

   Anyway, in the case of Ubuntu liveCD, I used the instructions in comment 
16 to be able to mount my raid volumes - and in that case, the module name 
is dm-raid45, not 4-5.
