Welcome back Leo!
I haven't tried v0.8.5 yet, still on 0.8.4 but running into an issue that's causing some bizarre issues. I picked up a Class 10 16GB SD a couple weeks back and decided to partition it out for ext3. Using AmonRa's recovery, I split the card up and upgraded to ext3. I actually have a 512MB swap part, 4GB ext3 part and the rest 11.5GB as fat32--I know swap and ext3 is overkill, but better have too much than not enough. So using your method of A2SD I have ata, and media going to the SD, leaving Dalvik alone.
At first there were the occasional random boot, but figuring that it may just be me overloading the system or something. But then something odd started happening, everything, slowly, started to FC on me. Google framework, shop savvy (which I haven't even used yet), ADW, Dolphin HD, etc. And if I tried getting back in to whatever app, would immediately FC. After sifting through aLogcat, started seeing refs to either SQL trying to write to a read-only db or java missing a file in \data\data\java... I'm starting to think that I'm loosing access to either a partition or a specific folder. Once I reboot everything is back to normal for another hour or two--longer if it's idle. I tried to look into the \data folder in Astro, but it's empty, even when it's working fine.
So for starts, did I mess up in using A2SD and setting it up? Should I just stick to apps and leave data and media alone? Is your implementation of A2SD actually using the swap part? There a means of checking card integrity without having to plug it into a linux box?
Stuff gets confusing.
Update: Installed the new version after wiping system, cache, dalvik, ext3, battery... restored apps only and it worked for a bit, but then the FC's started up and once that happens then only thing to do is reboot.
