I definitely had the same issues others reported with the 20.00.00.00 
firmware (though using FreeBSD 9.3). I was building a new system at the 
time so was able to stress test it with different firmware versions - 20 
gave errors, 19 and 16 were fine.

I have another system which isn't in production yet - I can do the same 
test on that and see if the newer 20.00.00.04 is stable. This is also 
running 9.3 but the test should still be valid. I will be using this 
system for 10.2 testing, but would like to keep it on 9.3 for a short 
time to try and resolve any issues with that.

I wonder if some advice about firmware could be added to the mps man 
page? Even at this point I'm not certain what the absolute best practice 
is, whether driver and firmware versions should match, or (as FreeNAS 
developers seemed to imply) firmware should be >= driver.
