I've noticed that the kernel itself sometimes uses a lot of CPU to
perform JFFS2 garbage collection, a while after you write/delete a lot
of files. If I'm not mistaken, and that's the case, it could explain
why the CPU is 100% busy, but top doesn't see any process keeping it
that busy.
Check kernel messages with dmesg, perhaps there will be some clues
there?
