Public bug reported: The following applies to the 3.13 in trusty.
When transferring data at >= around 100Mbps, the IOMMU logs errors such as: AMD-Vi: Event logged [IO_PAGE_FAULT device=01:00.0 domain=0x001c address=0x0000000000003000 flags=0x0050] I have locally cherry-picked 7a9810e7bd99: r8169 "Enable RX_MULTI_EN for RTL_GIGA_MAC_VER_40" to the Ubuntu-3.13.0-37.64 kernel and confirmed this fixes the issue for my card as well. Please consider this for backporting to the 3.13 stable tree. The hardware is: % lspci -s 01:00 -vvvn 01:00.0 0200: 10ec:8168 (rev 0c) Subsystem: 1462:7721 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 96 Region 0: I/O ports at e000 [size=256] Region 2: Memory at fea00000 (64-bit, non-prefetchable) [size=4K] Region 4: Memory at d0800000 (64-bit, prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: r8169 ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1399999 Title: [PATCH] r8169 writes to memory not assigned to the device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1399999/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
