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.

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.

First set all your swappolube/whatever to defaults or uninstall so it doesn't interfere.
Then:
Unpack or perform your heavy IO load.Code:echo 8192 > /sys/block/mmcblk0/queue/nr_requests echo 8192 > /sys/block/mmcblk1/queue/nr_requests echo 1 > /proc/sys/vm/swappiness
After:
Code:echo 100 > /proc/sys/vm/swappiness
I found this helps alot with large IO.
Thanks!!!
