You have memory freed, but like your earlier page allocation failure on mount, it is too fragmented. This is an order-4 page allocation, the kmalloc() of struct pwc_device, and you don't even have any order-3 pages that are available. Are you running with CONFIG_COMPACTION enabled? If not, enable it and try again, or get root and manually try to defragment memory by doing echo 1 > /proc/sys/vm/compact_memory. If so, try killing a memory hogging process to free some memory and attempt to get some higher order pages available. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
