Thanks for links. I wonder why kernel doesn't decode these to be actually 
readable without a need for asking on ml - was decoding considered?

Anyway Adaptec support helped with details:

Basically this controller finds "bad stripes" and blocks any access to these 
areas resulting in errors :-/ What's more interesting there is no recovery 
procedure beside recreation. Fun :-)
