Are you using custom drivers? I was also trying to enable SR-IOV on this NIC for many tries, without succ= ess, but the name looks different, and these iflib settings from loader.conf are= not ignored: dev.ix.0.iflib.override_qs_enable=3D1 dev.ix.0.iflib.override_nrxqs=3D16 dev.ix.0.iflib.override_ntxqs=3D16 dev.ix.0.iflib.override_nrxds=3D"4096" Device names are ix# in my case: ix0: <Intel(R) X520 82599ES (SFI/SFP+)> port 0x2020-0x203f mem 0x92100000-0x921fffff,0x92204000-0x92207fff irq 44 at device 0.0 numa-domai= n 0 on pci5 ix0: Using 4096 TX descriptors and 4096 RX descriptors ix0: Using 16 RX queues 16 TX queues ix0: Using MSI-X interrupts with 17 vectors ix0: allocated for 16 queues ix0: allocated for 16 rx queues ix0: Ethernet address: 24:6e:xx:xx:xx:70 ix0: PCI Express Bus: Speed 5.0GT/s Width x8 ix0: Option ROM V19-b0-p12 eTrack 0x8000095c ix0: netmap queues/slots: TX 16/4096, RX 16/4096 ix1: <Intel(R) X520 82599ES (SFI/SFP+)> port 0x2000-0x201f mem 0x92000000-0x920fffff,0x92200000-0x92203fff irq 40 at device 0.1 numa-domai= n 0 on pci5 ix1: Using 2048 TX descriptors and 2048 RX descriptors ix1: Using 8 RX queues 8 TX queues ix1: Using MSI-X interrupts with 9 vectors ix1: allocated for 8 queues ix1: allocated for 8 rx queues ix1: Ethernet address: 24:6e:xx:xx:xx:72 ix1: PCI Express Bus: Speed 5.0GT/s Width x8 ix1: Option ROM V19-b0-p12 eTrack 0x8000095c ix1: netmap queues/slots: TX 8/2048, RX 8/2048 Nevertheless, when I try to enable IOV, it results in a constant panic: APEI Fatal Hardware Error! The platform is Dell PowerEdge R630 and has been tested many times in the p= ast on stable/14 and recently on stable/15. --=20 You are receiving this mail because: You are the assignee for the bug.=
