I just got another oops, which doesn't seem to be obviously related,
but I don't think I should file another bug report.
This oops occurred after I had:
* switched from wifi to wired ethernet (^C on dhclient; ifconfig
wlan0 down; dhclient -d eth0)
* ran an apt-get
I see the battery state is mentioned in the trace. The machine has
been running on battery for some hours now. So I have included the
output of
egrep . /sys/devices/LNXSYSTM\:00/LNXSYBUS\:00/PNP0C0A\:00/power_supply/BAT0/*
taken some minutes after the oops.
Ian.
