I see CC has moved to 3.18.29 and this kernel has the latest patch for a
jffs2 locking problem.

jffs2: Fix page lock / f->sem deadlock
[ Upstream commit 49e91e7079febe59a20ca885a87dd1c54240d0f1 ]
With this fix, all code paths should now be obtaining the page lock
before
f->sem.

I seem to remember this problem also causes the kernel to hang and was
intermittent depending on free space in the jffs2 partition.
People may want to try a CC build post this commit (today).
