Hi
Thanks for the quick response!
Now i'm on windows for a couple of hours (eek)
and sometimes it seems to stutter.. could be the fact its windows..
or it could be it is trying to kickstart the drive again somehow..
So, extra info: i had the problem before and after the samsung tools and other packages from the ppa where installed..
It could also be i have a foobar hard-drive..
I'll try to get the dmesg

(not easy to write it away when drive ain't responding..)
i think if i have also an ssh open.. i need to be able to save it

first i thought it was an filesystem issue.. but then i noticed i only have the problem when on battery..
note i disabled the harddrive sleep in power management so.. it shouldn't be going to sleep..
again.. could be foobar drive.. and it will be format 7 times and RMA

but then again.. it should also fail then on battery.. so idd.. place we need to search ACPI
I guess one of the first things is disable acpi on boot..
oh yeah.. since i upgraded to your kernel version sleepmode doesn't seem to work anymore.. but backlight is working like a charm

Thanks for the help! (great i found this forum)
