Issue 1: No update. Issue 2:=20 Actually Linux version of the driver has the same (similar?) issue and I reported it here: https://www.spinics.net/lists/netdev/msg420136.html Some people suspected that it failed to allocate a UAR, but after we increa= sed LOG_BAR_SIZE with mlxconfig from 3 (8MB) to 5 (32MB), the issue was still there. We'll continue to work on this. Issue 3: No update. Issue 4:=20 It looks this may be a host side issue. on Live Migration, the host just removes the VF from the guest by force suddenly. Working on this.=20 But meanwhile, the VF driver should be improved to be more robust to cope w= ith this scenario. --=20 You are receiving this mail because: You are the assignee for the bug.=
