Bug Description
CID : 201412-16338 SazanW-2
00:02.0 VGA compatible controller [0300]: Intel Corporation Broadwell-U Integrated Graphics [8086:1616] (rev 09)
08:00.0 3D controller [0302]: NVIDIA Corporation Device [10de:137a] (rev a2)
Repro steps:
1. Install 14.04.2 on SazanW-2
2. Execute upgrade by 'Software Updater'
3. Make sure kernel upgrade from 3.16.0-30 to 3.16.0-36
4. Reboot system and verify the result.
Actual result:
a, Booting, GRUB is pass, then system got hang and screen became black. tty1~7 are useless.
b, Try to add a 'text' kernel parameter on GRUB page, booting system, got the same actual result.
c, After system got hang, try to get logs via 'SSH', get result 'Connection refused'.
Notes:
Because there is no available NV driver, system is working on 8086:1616 now. Since I can not get any logs under 3.16.0-36, just attach all logs under 3.16.0-30 here.
