Firstly, I did not see the BUG with 2.6.24-rc5. Looking at include/linux/scatterlist.h suggested that CONFIG_DEBUG_SG has something to do with this. When enabled SG debugging, I also saw the BUG. Adding this patch solved the problem. You can add Acked-by: Kai Makisara if you want. This fix should be included in 2.6.24. -- Kai -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
