Seems like the issue related to the following errors I see in dmesg: [48459.391753] dmar: DRHD: handling fault status reg 302 [48459.392092] dmar: DMAR:[DMA Read] Request device [21:00.1] fault addr fbaddd000 [48459.392092] DMAR:[fault reason 06] PTE Read access is not set
I am running on HP ProLiant DL380p Gen8. Ubuntu 3.11.0-26-generic Is anyone encounter this kind of issue with Intel XL710 NICs (Fortville)?

Nissim Hi Yan Please tell me what version of firmware are you using? If it is too old, please update to at least 4.2.6. If it is still there, check that if your firmware updating is really successful. You can try to run linux kernel driver to have a double check.

For some reason this function reaches TIMEOUT for more than maximum allowed times (10 times). In the note below I understand that several failures may be considerable but not as many as I have. Should I enlarge the retries number ? Is it a HW issue ? Anyone who faced it or may assist please comment. Thanks, Yan
