** Description changed:
I have just made a regular upgrade on my ubuntu vivid machine. After
doing so the system freezes after login. I tried different accounts and
different window managers (xmonad and gnome fallback), but it freezes
every time a few seconds after login.
Because of the freeze I cannot report this bug using ubuntu-bug. So tell
me what files you need for debugging this (I have ssh command line
access to the frozen machine).
It might be relevant that the mouse pointer changes from a white one to
a smaller black one when it freezes.
After freezing I cannot switch to console via Ctrl+Alt+F1.
+
+ I tried to narrow it down by switching to the previous kernel
+
+ 3.19.0-30 works
+ 3.19.0-31 freezes
+
+ Then I diffed the output of dmesg with and without freeze. The relevant
+ part (when it is freezing) seems to be:
