I got a Mac Pro (2008) with a Rocketraid 2322. Now since 10.5.3 I got problems with booting the computer. Seems like Leo & Rocketraid don´t like each other very much. I´ve sent several mails to HighPoint but never got an reply. Removed all usb & firewire stuff - didn´t help. Also did a PRAM reset. So anyone here have any suggestions on what else I can try?
