I'd like to second this request, as I have two drives in a raid 5 array
that occasionally (once every month or two) suffer from a timeout, which
causes them to be kicked from the raid array.  SMART tests show no
problems, so it would be convenient if I could increase the timeouts.

(More details about my set-up are in this thread on the linux-raid list:
