Build 35 lags are due to some kernel changes made 8-9 may.
With ondemand and ondemandx governors everything will work fine, but with other governors you will experience lags.
Now everything is fixed.
I suggest to extract and flash kernel from Humberos today build over AOKP 35 to enjoy latest AOKP at full.
This kernel version includes some other backports from 3.x kernel, which makes everything even smoother (and min freq 100 working )
EDIT
Here you can download Humberos 2012.05.12 kernel for P1000
Extract boot.img and overwrite the one in AOKP 35 zip, then flash the rom as always.
Sorry for P1000L and P1000N users, now i have no time to upload latest kernel also for these version.
@stimpz0r: if you want me to remove the link, tell and i will do.
Thank You for all your efforts in porting AOKP (best ICS rom) for our tablet!!
