Zero problems so far, for me.
I've been messing around for about 2 hours now.. no freezes at all, no failures or unexpected behavior.
My 3ds is on 4.5 FWIW, using the 2GB packin SD card that came with the 3DS. GW diagnostic tests all complete with success.
I'm not tried any retail carts, just ROMs, emunand, eshop etc.
Emunand successfully updated.. went very smooth. I was worried because my 3DS had already downloaded the system update and had been nagging me for weeks to install. But it seems, that was not a problem for Gateway.

Edit: After a few days use I can confirm that I am also quite regularly getting a freeze when I try to enter the Gateway GUI (i.e. when you hold the L button).
