Title:
Wired Ethernet gone after resume from suspend -- Realtek 8168
Status in “network-manager” package in Ubuntu:
Confirmed
Bug description:
Binary package hint: gnome-network-admin
I am using a new HP dv7 laptop. To isolate the problem, I have
formatted the hard drive and performed a CLEAN installation. Here is
the version information:
/etc/issue:
Ubuntu 8.10 \n \l
uname -a:
Linux Ubu 2.6.27-7-generic #1 SMP Fri Oct 24 06:40:41 UTC 2008 x86_64
GNU/Linux
I perform only three actions on the clean system
(1) Install all updates. For today, this includes base-files,
linux-*-2.6.27-7*, linux-libc-dev, procps.
(2) To get suspend working I need to make sure the keyboard/mouse
fuctions. I have needed this fix from 8.04 and it is still a problem
in 8.10, but this easy work-around has worked fine for months: Add the
file "25i8042" to /etc/pm/sleep.d/
(3) Finally, my NIC comes up as a Realtek r8169, instead of r8168.
This is another long-known about bug, so I follow the RealTek
directions from their website and then blacklist the r8169. Here are
some output to show success:
lsmod | grep r816
=====================================================
r8168 45968 0
dmesg | grep r816
=====================================================
[ 15.366988] r8168 Gigabit Ethernet driver 8.009.00-NAPI loaded
[ 15.367025] r8168 0000:0a:00.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19
[ 15.367051] r8168 0000:0a:00.0: setting latency timer to 64
<snip>
[ 31.867892] r8168: eth0: link up
At this stage everything is working on eth0. Also, but I believe
unrelated, I can connect to wlan0 without issue.
Next, I go into suspend and come back. eth0 is "grayed out" on the
Network Manager drop-down and neither a modprobe -r r8168, modprobe
r8168 nor a reboot will bring eth0 back to life. Wireless, however is
still okay. Currently nothing is showing in ifconfig for eth0.
I have spent hours and hours looking at other similar bugs with
potential fixes, and nothing seems to help. Hopefully, I've just
missed something - but at this stage I am asking for some help to
resolve. If any other information is required, please let me know.
