Yes, it hung, but I didn't have time to debug the root cause until
today.

The reason is that the OMAP1 DMA IRQ numbers used in mach-omap1/dma.c
have no basis in reality. So doing a memory-to-memory transfer using
*all* channels results in spurious interrupts, then hangs.

Will post details in reply to the OMAP1 patch (7/9).
