Ubuntu 13.10 Reboots Instead of Shutting Down
January 1, 2014 8 Comments
The last few days I was struggling to find the causes of a peculiar issue. Ubuntu 13.10, given the conditions detailed below, would reboot instead of shutting down.
- Suspend computer by closing lid
- Resume computer by opening lid
- Select shut down from the menu
The expected behavior is that the laptop would shutdown, but what actually happened is a shutdown followed within two seconds by a reboot. I posted a question on Askubuntu asking what logs I should look at and I posted on the Ubuntu forums looking for any advice at all. I continued my own trouble shooting and found the culprit was the newly acquired Anker® Uspeed USB 3.0 7-Port Hub + 5V 2A Charging Port.
Two different computers had the issue with the hub attached. I tested on a Lenovo T530 and X230. The Anker uses the VIA VL812 chipset and my research on that shows other manufacturers advertising that they have updated firmware (v8581) on their devices. I was unable to determine what firmware the Anker was using and their website did not offer any firmware upgrades. There is also a VIA VL812-B2 chipset that Anker and other manufacturers are advertising as well.
Ubuntu users looking for a USB 3.0 hub may want to avoid the Anker 68UPHUB-B8U and potentially the VIA VL812 chipset.
