Highpoint ssd7140 in mac pro

Anyone running a ssd7140 8x card? ive gotten a rma on mine and its still acting up.

After larger transfers the whole thing would lock up, cant reboot, finder crashes , if I use the terminal to cd to the drive terminal would crash.

I am pretty much out of ideas, ive put it in a linux workstation to test but I kinda think there is a issue with this particular card and the mac pro, found 1 other person with similar issues on macrumors
