I've been rocking 2.5 (kernel, Rom and recovery) all day and absolutely no problems.
I also noticed new wallpapers, so DJ either added some (thank you!) or I've just overlooked in previous builds (belated thank you).
Edit: I see the new wallpapers in the changelog. Maybe I should read? Thanks again.
I'd highly recommend trying out the GeeWiz kernel. You may be experiencing problems because the KGB kernel isn't based on EH03 unless it's been recently redone. It's based, I believe, on EI20 which might be the source of your frustration.
DJ's kernel is fast and clean. Combine with his Rom and you have a very fast, stable, and clean phone OS experience.
So the kernel may be your issue, though I don't know.
2nd Edit: I see the KGB kernel is now EH03 based... my bad... so not sure what to tell you.
On the other hand, my Fascinate gets to acting weird (like your description) if I don't reboot for several days.
Either way, download and flash the new version. It is awesome! If 2.4 is working for you, 2.5 will be even better.
Right now, GeeWiz is the only Rom I'll run! Thanks!
