Ahh big surprise, I can mount my other btrfs partitions (4 on 2 HDD) all of a
sudden. 
I wonder why, because I tried before and I got a crash with all of them. 
The only difference now is that I took the SSD with the 5th partition out.
I have a boot partition as ext4 on that same SSD drive which I can mount
w/o problems. So I think it's not the SSD itself that is buggy.
