Sure thing, though that is almost exactly it. The bottom decal only has HP Pavilion a1630n though there is another sticker with Microsoft Windows XP Media Center Edition and it is definitely a desktop. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1301558 Title: 0cf3:7015 [ath9k_htc] 14.04 NetworkManager hangs after 'ath: phy0: Unable to remove station entry for...'
