Huh?  Yocto 1.5 ships with the 3.10 kernel (and Yocto 1.6 should be
shipping soon with an even newer kernel.)

2.6.37 dates back to 2011, and there have been a *huge* number of bug
fixes since then.

If you can't upgrade to a newer kernel, you might be better off
falling back to ext3, and see if the problem still presents itself
there.  Ext3 will create much more flash wear, but that's the price you
pay for staying on an ancient kernel.  :-)
