Default [Q] wanamlite freezing after update

Hi, I recently updated my phone (i9300) from custom ROM wanamlite 6.8 to 7.3, and also updated the kernel to Adam 3.0, and now im facing some problems

1) It takes 4-5 seconds for the screen to wake up after pressing unlock.

2) every time I play music, the phone becomes very sluggish and the music skips so much to the point that I can't recognize which song is playing.

I really love this ROM and would love to continue using this version, but I need to gets these things fixed. Pls help!
