I'm affected as well for FreeBSD 12.0-RELEASE-p7. kernel: igb0: TX(0) desc avail =3D 1024, pidx =3D 0 ... kernel: igb2: TX(5) desc avail =3D 1024, pidx =3D 0 igb0@pci0:129:0:0: class=3D0x020000 card=3D0x00001458 chip=3D0x1521808= 6 rev=3D0x01 hdr=3D0x00 vendor =3D 'Intel Corporation' device =3D 'I350 Gigabit Network Connection' class =3D network subclass =3D ethernet igb2@pci0:132:0:0: class=3D0x020000 card=3D0xa02c8086 chip=3D0x10e8808= 6 rev=3D0x01 hdr=3D0x00 vendor =3D 'Intel Corporation' device =3D '82576 Gigabit Network Connection' class =3D network subclass =3D ethernet Use case (forced by me but generally it happens randomly): 1. All was working. 2. I detached Ethernet cable from modem side. 3. Connected again and saw "no carrier" on igb0 interface. 4. System logged as follow: Jul 5 22:31:35 hpv kernel: igb0: TX(0) desc avail =3D 1024, pidx =3D= 0 Jul 5 22:31:38 hpv kernel: igb0: TX(0) desc avail =3D 1024, pidx =3D= 0 Jul 5 22:31:40 hpv kernel: igb0: TX(0) desc avail =3D 1024, pidx =3D= 0 5. I was trying "server:# service netif restart igb0 && service routing restart" without success. 6. Resarted OS to back to normal. Is there any workaround instead of restart a system? I was trying below without progress as well. # ifconfig igb0 down # ifconfig igb0 up I think the problem is when the network card loses ethernet link and then errors occurs with non-working interface?! --=20 You are receiving this mail because: You are the assignee for the bug.=
