SSD on osx 10.10

Hi there

Any one having trouble with SSD drives on OS X 10.10 - yesterday i mounted a SSD drive as my second drive i a Mac mini. My plan is to use it as my media drive and leave the os on the spinning apple drive.

But here is the problem ... When i boot the drive is there but when i start using the drive im loosing it and Isadora crashes.

Any ideas ? reinstall 10.10 or downgrade to 10.9 ?

It is from kext signing, a new feature, similar to driver signing in windows, your options are few

@xlrstik
and this is running ok now but with an OWC SSD instead?
I have been using two from One World Computing SSD's in my i7 17" 2010 MBP with great results. I have Mavericks on one SSD and Yosemite on the other. No problems so far, and very fast.
For the price, it feels like having a new machine... but I have still have all my firewire/expresscard slot etc.
