Seveirty: serious
Hi!
Since some time now (I only sat down to track it down pretty recently,
but this has going on for probably a year or more), laptop-mode-tools
has broken the wired network (e1000e) whenever I unplug the laptop from
the wall power.
The culprit is BATT_THROTTLE_ETHERNET=1 in
«/etc/laptop-mode/conf.d/ethernet.conf».
This turns the working ethernet device from this state:
,---
# ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10ba
100baseT/Half 100baseT/Full
1000baseT/Full
Supported pause frame use: No
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10ba
100baseT/Half 100baseT/Full
1000baseT/Full
Advertised pause frame use: No
Advertised auto-negotiation: Yes
Speed: 100Mb/s

To this non-working state:

# ethtool eth0

If I set BATT_THROTTLE_ETHERNET to 0, then everything works as before.
I don't think this setting should be enabled by default if it might
cause this type of breakage, even if it ends up being a driver
problem.
thanks,
