Comment # 3 on bug 1137686 from Lee Duncan

I have no experience with this config option, and no knowledge of why it is not
enabled for SUSE, but it seems like a "good thing". There are some older
references I found on the web to this option having issues with some devices,
with realtime linux, and on the s390 architecture, but I _believe_ all issues
have been resolved, and it is worthwile, particularly on systems with lots of
storage over multiple buses.

Hannes?
