*** This bug is a duplicate of bug 1680904 ***
https://bugs.launchpad.net/bugs/1680904
Over on the bug where I initially brought this up, Rocko tells me:
===
your lockup looks like
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1680904 (and the upstream
bug is https://bugs.freedesktop.org/show_bug.cgi?id=100516). It's a bug in the
Intel graphics drivers that unfortunately is present in both kernels 4.10 and
4.11, but should be fixed in 4.12.
===
Indeed, my kern.log looks very similar to the output in the first
comment on that bug. So I've marked this as a duplicate.
** This bug has been marked a duplicate of bug 1680904

Title:
Random system lockup with " BUG: unable to handle kernel NULL pointer
dereference at 0000000000000018", "IP:
gen8_ppgtt_alloc_page_directories.isra.38+0x115/0x250 [i915]"
Status in linux package in Ubuntu:
Incomplete
Bug description:
When starting a Firefox compilation job earlier today, my system
locked up; ctrl-alt-f1 had no effect, etc. (I was able to restart with
the REISUB technique.)
I'm on 64-bit Ubuntu Zesty, and I was running a kernel version that's
currently in zesty-proposed to have the fix for
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1674838 .
"uname -a" output:

Here's the relevant snippet from kern.log when the hang happened:
