[elrepo] CentOS/Kernel 3.18/Thunderbolt2

[israel]

I just got a new SuperMicro box with a AOC-TBT-DSL5320 Thunderbolt2 card 
pre-installed. I installed CentOS 6.5, ran yum update, and then, because 
to my understanding at least, thunderbolt support was added in kernel 
3.10, I went ahead and updated to kernel 3.18 from ELRepo. This all 
appeared to work fine, and my system came back up running kernel 3.18 as 
expected, but when I plugged in a thunderbolt hard drive there was no 
indication that CentOS recognized the drive - even after a re-boot. Am I 
missing something, such as needing to install a special driver for this 
thunderbolt card, or the drive being identified differently than sd? Or 
does Linux/CentOS simply not support Thunderbolt2? Thanks.
