Stressing this SX8 card broke with CARM_MAX_Q anything higher than 16. Tests included simultaneous iozones, bonnie++'s, fsx, badblocks, and mkfs'ing, on 4 ports. Setting CARM_MAX_Q to 17 or above resulted in errors such as: Buffer I/O error on device sx80_0p1, logical block 108828 lost page write due to I/O error on sx80_0p1 end_request: I/O error, dev sx80_2, sector 389167 It's been thrashing away with various tests most of today with CARM_MAX_Q = 16, and it hasn't missed a beat. Thanks must go to Matt Johnston who actually did all the work of giving the card and drives a hard time.
