This is an amd64 laptop, Dell Latitude 3340.
I updated from:
11.0-CURRENT #1 r298975: Tue May 3 15:18:03 BST 2016 /usr/obj/usr/src/sys/GENERIC amd64
to:
11.0-CURRENT #2 r300212: Fri May 20 09:50:53 BST 2016 /usr/obj/usr/src/sys/GENERIC amd64
Now em(4) stops working 2-5 min after boot,
or, perhaps, after 2-5 min of network traffic.
The interface is shown as up:
# ifconfig -a
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=4019b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,VLAN_HWTSO>
ether 20:47:47:01:62:6e
inet 10.70.14.139 netmask 0xffffff00 broadcast 10.70.14.255
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
media: Ethernet autoselect (1000baseT <full-duplex>)
status: active
and there's nothing obvious in dmesg or /var/log/messages,
but the network is not working at all, e.g. can't ping
/etc/resolv.conf hosts.
Is anybody else seeing this?
Thanks
Anton
