Just tested the new kernel. It installs ok using the KernelUpdater.zip file and the phone boots, but I've had to revert to the original kernel, since this new one seems incompatible with Link2SD, or at least my setup.
The second partition on my SD is in FAT format, since my old phone (a Chinese clone) didn't support ext2. Using the stock kernel it works like a charm.
After upgrading to the new kernel, Link2SD showed no linked apps, so I tried recreating the mount script. Then, after rebooting the phone again, I still couldn't see any apps, so I tried using the new "relink" function, which I used succesfully after upgrading to Technoduos. It throws me the following error: "Link failed Operation not permitted" and I can't use any of my linked apps.
Maybe I should convert my second partition to ext2?

1) As I said before, new kernel looks incompatible with Link2SD, at least if the second partition on the sd card is FAT
2) If you go to Google Play and try to install A2SDGUI, it will download and, just when it tries to install, the phone reboots by itself. After the reboot, nothing is installed.
