[monochromec <monochromec@xxxxxxxxx>]

Got to the bottom of this: root cause was a heavily hacked version of
BCMWL (6.20)  which I manually introduced in Trusty due to the severe
shortcomings / instability of both the FOSS b43 driver and the repo
version of Broadcoms hybrid driver (which I think was version 6.30 at
the time). A re-installation of the relevant broadcom-sta packages from
the Vivid repo fixed this problem and reintroduced stability for the
kernel once again.

BTW: The DKMS version of the package broadcom-sta-dkms doesn't compile
on the Vivid stock kernel (3.19.0-15), due to header incompatibilities,
I'll open a new bug report for this. Let me know if I should do the same
on kernel.org.

  Triaged
Status in linux source package in Vivid:
  Triaged

Bug description:
  Installation of 3.19.15 as part of Vivid upgrade causes machine to
  freeze after Lightdm has displayed login screen. Trackpad / keyboard /
  USB mouse don't work, machine isn't visible on network. Same happens
  with kernel versions 4.0, 4.0rc7 from the Ubuntu mainline kernel repo.
  Fan spins up audibly after 30 seconds of login screen display.
