Hi all!

Yesterday I installed Yosemite on my 4.1 Mac Pro, everything went fine. today I enabled Trim with Trim enabler, I restarted and then I got a grey screen with a circle and a slash.

I tried to boot up in CMD > V mode, and got this.

I also tried Target mode with my MBP. My Boot SSD from the Mac Pro appears? But why can't it boot.

"still waiting for root device" What does it mean.
