Yes! I think your rpm installation is correct! Thanks! It looks like the v3.6 driver did not affect the issue. However I think I can not just test driver only, maybe we should test by changing the whole kernel due to it may has another fixes in neworking or other related subsystem.
Actually there already had a bisected result, it may related to the issue (from: https://bugzilla.kernel.org/show_bug.cgi?id=54021#c14) commit 69b08f62e17439ee3d436faf0b9a7ca6fffb78db Author: Eric Dumazet <eduma...@google.com> Date: Wed Sep 26 06:46:57 2012 +0000 net: use bigger pages in __netdev_alloc_frag We currently use percpu order-0 pages in __netdev_alloc_frag to deliver fragments used by __netdev_alloc_skb() Depending on NIC driver and arch being 32 or 64 bit, it allows a page to be split in several fragments (between 1 and 8), assuming PAGE_SIZE=4096 Switching to bigger pages (32768 bytes for PAGE_SIZE=4096 case) allows : - Better filling of space (the ending hole overhead is less an issue) - Less calls to page allocator or accesses to page->_count - Could allow struct skb_shared_info futures changes without major performance impact. This patch implements a transparent fallback to smaller pages in case of memory pressure. It also uses a standard "struct page_frag" instead of a custom one. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1175091 Title: Cable Ethernet conn.
