There is a thread for increasing responsiveness under high IO, search it. Also you may try my settings from here, those are made especially for high IO load.

Re: N900 reboots on high load
 
Sorry for the late answer, I had no spare time playing with it.

Now I've tried it again and set /sys/block/mmcblkX/queue/nr_requests to 8192 and it solved my problem.
I didn't have to modify anything else.

Now I could debootstrap Debian to my loop device and also I can install applications to the system without any reboots on the device.

It works well.

So, thank you very much your help, you helped me a lot.

Then:
Code:
echo 8192 > /sys/block/mmcblk0/queue/nr_requests
echo 8192 > /sys/block/mmcblk1/queue/nr_requests
echo 1 > /proc/sys/vm/swappiness
Unpack or perform your heavy IO load.

After:
Code:
echo 100 > /proc/sys/vm/swappiness

I found this helps alot with large IO.
Just gave it a try - I/O eMMC<->Micro SD are back to normal (fast).

Thanks!!!
