It's fine where it is now, as long as you've set up enough memory to hold it. You can always change it later.

You shouldn't receive any interrupts after that.

Ok, thanks. I do not receive interrupts after the "cli" instruction, of course.

Looks like I solved this problem by using interrupt or interrupt-like stack for task switching.

Interrupts are not necessary for task switching, so I really have to wonder why it didn't work for you.
