Comment 35 for bug 190754

I don't think this to do with hardy only , i experienced this problem with my brand new desktop before 3 months back when i tried to install Ubuntu gutsy 7.10 on it , the spec where : intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz - 2 GB of memory , i tried the alternate installation also and get the same problem , finally i managed to get rid of it by installing Ubuntu Studio 7.10 which has a different kernel ( 2.6.22-14-rt ) the problem gone and every thing was fine , yesterday i installed hardy heron beta and I'm now having the same stutter in sound even if I'm not moving the mouse cursor or opening any application , tried to stop using compiz and close many applications but still the same.
I tried to change all devices to alsa , but still getting the same stutter
Another thing i noticed but not sure if its related to this bug , when i was using Ubuntu studio 7.10 i was not able to do a memory test from
grub screen i was getting this error : Error 28 : selected item cannot fit into memory
and now i cant do it also.
I feel that something is wrong with the kernel itself. ( just my feeling )
