Hi Lasse, Hate to punt you but the right way to try to get resolution for this is going to be through the official Dell support. Aside, there are probably several avenues to resolution. Mellanox may be able to offer some change that will let this work on C6145.

After rebooting with SR-IOV/IOMMU options enabled mlx4_core fails to load just after the following in dmesg: [ 51.887808] AMD-Vi: Event logged [IO_PAGE_FAULT device=41:00.1 domain=0x0000 address=0x00000037f7beb000 flags=0x0050] [ 51.947372] AMD-Vi: Event logged [IO_PAGE_FAULT device=41:00.1 domain=0x0000 address=0x00000037f7beb080 flags=0x0050] [ 52.007661] AMD-Vi: Event logged [IO_PAGE_FAULT device=41:00.1 domain=0x0000 address=0x00000037f7beb0c0 flags=0x0050] [ 52.069120] AMD-Vi: Event logged [IO_PAGE_FAULT device=41:00.1 domain=0x0000 address=0x00000037f7beb040 flags=0x0050] (4 VFs configured, device=41:00.0 is the device I'm targeting and device=41:00.1 being the first VF) I have contacted Mellanox support but they reckon it's a platform issue. Both the sled and card have latest firmware, running Ubuntu Trusty and I have tried multiple kernel and OFED configurations to no avail. Running through similar steps on a Dell R630 (Intel) seem to work fine. Also here in some more detail: https://community.mellanox.com/thread/3298 Any suggestions and pointers are welcome.
