I tried it last night with the latest and greatest Vanilla BK + libata + libata-dev and really pounded the poor machine hard with very rude bash scripts doing SMART polling from two separate tasks (so randomly I would poll the same drive with two different queries simultaneously) and I could certainly fail drives out of the array, but no oops. So yes, SMART is causing timeouts but no longer causing an oops here. Now I have also replaced the PSU with a much better specced unit, so that may have also been a contributing factor to the oops. (The 12v rail was running on the edge). If this rebuild this morning gets through then I'll go back to the old kernel that was oopsing and try it again to compare.
