Ok, I found the bugger: It *IS* the sheduler. I tried elevator=deadline and all stuttering went away. Before I was using as. mm1 used default sheduler (as I think) and ther eno probs. So the (updated?) as sheduler in mm2 has a problem...

Can you run the attached script when you repeat the test?
With both elevator=deadline and without.

./ hdc

Your problem sounds a little like the one I'm seeing, only I'm seeing it
with both deadline and as. I can't really see if I'm loosing
timer-interrupts or not since the only way I've found to reproduce it is
to recieve a file via network and write it to disk, and that generates
lots of interrupts...



A ! is missing there... Only 0 are appearing...what is expected? Do I have do do anything else?
