That looks to be part of the problem here ... failing an order=3 allocation during boot on a system that just a few lines earlier in the boot log reported "Memory: 37474000k/37680640k available" looks bad ... but perhaps having *more* memory is part of your problem. You may have run low on GFP_DMA memory because some allocation scaled by memory size has chewed up a lot of your memory. To check this try booting with a "mem=4G" parameter and see if that helps you. But it is also bad that the swiotlb() code failed to handle this. Can you check whether the problem is related to the size of the allocation being just over 256K (a magic number for swiotlb since IO_TLB_SEGSIZE is 128 times a slab size of 2k). Try changing lib/swiotlb.c to set IO_TLB_SEGSIZE to 256 instead. -Tony - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
