I am seeing the same behavior with the pgprot_dmacoherent(). I > pulled your patch (which got applied cleanly on 2.6.32-rc5) - What happens if you comment out the pgprot_dmacoherent() / pgprot_noncached() line completely? I suspect that will "solve" the problem - but you'll then no longer have DMA coherency with userspace, so its not really a solution. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
