  BUG: unable to handle kernel paging request at ebe0

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Similar to LP: #1503568 and LP: #1503754, but on Vivid.

  After rebooting on the freshly installed 3.19.0-31-generic kernel, I'm
  able to login on lightdm and see the desktop, but I have no network
  and I'm not able to poweroff/reboot/logout via the UI or via the
  terminal (the command just hangs).

  In the dmesg I have the following oops:

[Kernel-packages] [Bug 1503786] Re: BUG: unable to handle kernel paging request at ffffebe000000000

2015-10-07 Thread Federico Fissore
Happens with my 3.16.0-51-generic kernel, since the moment I updated
from 3.16.0.50.41 to 3.16.0.51.42, this morning

Title:
  BUG: unable to handle kernel paging request at ebe0

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Similar to LP: #1503568 and LP: #1503754, but on Vivid.

  After rebooting on the freshly installed 3.19.0-31-generic kernel, I'm
  able to login on lightdm and see the desktop, but I have no network
  and I'm not able to poweroff/reboot/logout via the UI or via the
  terminal (the command just hangs).

  In the dmesg I have the following oops:
