Thanks Janaka,
The interval has to be precisely 100 microseconds, Its for real-
time data aquisition.
Yes U are right, I have to use a hardware timer (e.g HPET
(most favourable), APIC timer OR TSC ).
I'll do some research on the pre-emptable linux kernel...
Since I'm new in this stuff it would be great help if U could point
me to some resources, code OR first hand info...Thanks again man!!!

From the sound of it you seems to be working on a x86 platform. I
work in on a PowerPC platform, hence my advice on timers probably will
be useless to you since they are architecture/processor dependent.
However for general kernel development and kernel based timer info,
you can always refer to the book "Linux Device Drivers" 3rd edition by
Rubini.
