[Bug 1399999] [NEW] [PATCH] r8169 writes to memory not assigned to the device
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:
