Shaneee Posted July 1, 2012 Share Posted July 1, 2012 I bought and installed the AR5B91 for my Lion Laptop. All was good on 10.7 but I updated to 10.7.3 and recieved the 'still waiting for root device' error. I removed the card and it booted fine. How can I get this working fine? One error on boot I spotted just before still waiting for root device was PCI open failed. Thanks.
