Trying to boot CentOS 6.6. Have adopted kernel-lt from elrepo which is 3.10 and supports EFI. My problem comes when trying to mount the root filesystem. Any ideas or debugging suggestions will be appreciated!

Thanks,

So make sure it is an 3.16 or later kernel and try again.
I also know mcb30 have posted the link to that issue and patch that was added in 3.16 - but can't find it right now.
Also you posted a new thread about CentOS 7 - but no information about which kernel version is was (or atleast not as far as i could tell)

Sorry my bad about your other thread, was just hard to see, will just quote relevant part here for reference.
