[Bug 1288411] Re: udev restart on upgrade broke my wireless state

[Steve Langasek]

$ rfkill list
1: tpacpi_bluetooth_sw: Bluetooth
	Soft blocked: no
	Hard blocked: no
2: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
17: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
$

Certainly there's nothing soft-blocked now; there also shouldn't have
been at the time since the wireless was actively in use until the udev
restart, but I didn't check the rfkill output at that moment so I can't
say for sure.

A fresh 'sudo service udev restart' here does not reproduce the initial
failure, so I guess it's a transient error and if no one else sees the
problem we can probably close it.  But let's leave it open/incomplete
for a while in case this is reproducible by someone else.

Yes, this was a trusty daily upgrade.  I'm attaching the output of grep
'2014-03-05 12:3.*\bupgrade\b' /var/log/dpkg.log, showing the set of
packages that were part of the upgrade in question; I don't see anything
hardware-related in there aside from udev, but maybe you'll spot
something that I didn't.

Title:
  udev restart on upgrade broke my wireless state

Status in “systemd” package in Ubuntu:
  Incomplete

Bug description:
  Upgrading on trusty today, my wireless connection suddenly cut out,
  with network-manager reporting that "wireless is disabled".  Looking
  at the logs, I see that udev was upgraded, and that as part of that
  upgrade udev was restarted.  I had to toggle the wireless switch on my
  laptop off and on again to get the wireless to come back.

  I don't know why udev is being restarted on upgrade in Ubuntu - this
  is a delta from the Debian package, where udev is never restarted.
