You seem to be contradicting here. If ISR does not
have a context then how can it get preempted by a
kernel thread(on 2.6 or anywehere else???) Are you
talking about the Timesys kernel here; they have
changed the kernel to run an ISR in a process context.
In such a case you can preempt the ISR but on regular
kernels this is not possible.
Yes i said i made a mistake :) ISR cannot be preempted.
