X2 MR2 - SD Card detection problem

[#1]

My X2 was ported with MR2 (Generic_SG) which resulted to stability compared to the previous version.  But lately experiencing intermittent SD Card detection problem.  I have to reboot just to detect the card.  Any solution for this?  or this is going to be address by MR3?

I got a fix from XDA developers too (I assume the same as above), and it's made the phone much more reliable.

Haven't had a single storage card problem since, and I believe less hangs (still more hangs than a production standard phone should have though)
