Comment(by wad):
You can find a save-nand image from laptop JFFS1 (the one that has crashed
repeatedly) at:
http://dev.laptop.org/~wad/nand/crash/
The write throughput of a laptop running JFFS2 degrades greatly over time.
The laptop gets to a state where data which could be previously written
can no longer be written. Even after freeing up another 32 MB (only 20MB
was being written)so the test can proceed, writes remain very slow. For
timings showing this happening to two different laptops, see:
