Do you think does it make sense to no= te > that Linux commit, and Linux kernel version that has been introduced? >=20 Hi, Ferruh At beginning, we found this issue in latest kernel version, such as kernel = 4.7.9 on fedora24. But later, we observed that this issue also exist on REL7.3. So, it may be a little difficult to us to figure out exactly which kernel v= ersion doesn't support. And the root cause is the HW's errata which makes uio_pci_= generic cannot be used on XL710 series NICs. Thanks Jingjing
