What from? and for what reason?
I'm finding 3.4 quite stable.  3.5 does seem to have some problems.

There should have been some lines before that which are important.
Possibly : omap_dma: You need to stop the DMA channels before unlinking
or       : omap_dma: trying to unlink non linked channels

Also, is this the 3.2 kernel?  I assume so.
