wired network sometimes not functional on bootup

Asked by gregrwm on 2015-05-27

if i watch the nic while booting i see the LEDs go out several times, which i presume to correlate with hardware resets. after each reset, the LEDs stay out for several seconds, which i would say is longer than usual for most nics. after the final reset the system comes ready for login before the LEDs come back on. the network is functional on approximately 70% of bootups, but is not functional on approximately 30% of bootups. from these observations i'm guessing the driver is not waiting long enough before giving up during initialization.

can anyone clue me what to tweak, what to investigate, what further info to provide, or against what package i might file a bug?

/etc/udev/rules.d/70-persistent-net.rules contains:
 # PCI device 0x8086:0x10bd (e1000e)
 SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:21:70:32:6a:ee", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

/etc/network/interfaces contains:
 auto lo
 iface lo inet loopback

 auto eth0
 iface eth0 inet static
    netmask 255.255.255.0
    address 192.168.0.93
    gateway 192.168.0.91
    dns-nameserver 8.8.8.8

Have you tested your RAM health using Memtest86?

ok ran that, completed no errors

 e1000e 211354 0
 ppdev 17391 0
 pps_core 18758 1 ptp
 ptp 18861 1 e1000e

the above is excerpted from lsmod.
which .deb contains the e100e driver?

Can you help with this problem?
