Seeing the same problem here on a desktop machine when doing dd of 40GB image.
Couldn't log in via ssh until dd was finished.
This was repeated in dmesg every 120 seconds:
[ 2520.696276] INFO: task ionice:2393 blocked for more than 120 seconds.
Colin: your suggestion
echo 10 | sudo tee /proc
@Gema, I've now been able to reproduce this. I've found that the
following helps reduce the problem on my desktop:
echo 10 | sudo tee /proc/sys/vm/dirty_ratio
Can you try this and let me know if this helps.

I tried this, and didn't help the i/o activity.
I have also tried my old oneiric kernel, 3.0.0-19generic33, and it does
exactly the same thing. But I had never seen this problem before, so
maybe it is not in the kernel but in some user-side configuration?

Can you try:
echo "deadline" | sudo tee /sys/block/sda/queue/scheduler
and see if that helps with interactivity while doing the heavy write
I/O activity. Thanks!

OK, so I hadn't realized the machine was a desktop, hence the vm
settings are fairly low anyhow, so we shall scrub that idea above.

So, I suspect we have some conflicting requirements for the I/O
operations which aren't helping here. If you are running firefox I
suspect it may be issuing occasional fsync() calls which isn't helping.
My current hypothesis is that the virtual memory tuneables may need
tweaking to match your mem
