Public bug reported:
Since upgrading to ubuntu 17.04 from 16.10 my system will randomly
freeze after a few hours. Initially the display will stop updating then
audio will stop playing. Nothing but a hard reset can fix it. I have
attempted to switch TTY and use alt+sysreq+1 then alt+sysreq+t still
nothing.
I can't work out how to reproduce this issue but it happens seemingly
randomly fairly often sometimes while the computer is not in use and
locked. I tried switching from unity to gnome to solve the issue but I
have the same problem.
Here are the lines in syslog right before the crash
