I had hoped things improved :( when I was having problems with my mvsas based
card, there was someone making commits to the code from marvell and I got some
kind of response once or twice, but stopped replying and problems were never
fixed.
I however haven't had any real issues with my dirt cheap ($50-100) IBM M1015
cards (I have three). A lot of people have had good results with them.
Technically its a 9220, which is quite similar to a 9211, but has some slight
differences.
