I have a 5,1 with an XP 941 hard drive installed, and when I tried to upgrade it to 10.10, twice I got the gray screen on startup. I restored from a backup and tried again. Same thing.
I tried booting in safe mode, which was no help. I reset the PRAM, which fixed the problem. I just thought I'd share my experience in case others (the other 10 people dumb enough to buy an XP941 before cheaper alternatives came available) had the same problem.
For what it's worth, I do have Trim Enabler, but disabled it before the update.
