--- Comment #1 from IPTRACE <arkadiusz.majewski@iptrace.pl> ---
Hello!

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?!
