Mystery solved: had to probe another module. Wait, wait, I can defend myself :) What led me to believe the controller was autoprobed during boot is that mdadm complained about *sdd*, but not about sd[abc], hence I assumed [abc] were all fine. Plus, I didn't have to probe the module manually after boot was completed (appears that at that point some other module inserted it as a dependency). So - is that how mdadm (or the kernel?) handle raid, is the last disk checked first by design?
