Cassady, thank you for reporting this and helping make Ubuntu better.
At your earliest convenience, could you please test the latest upstream
kernel available from the very top line at the top of the page from
http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release
names are irrelevant for testing, and please do not test the daily
folder)? Install instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow
additional upstream developers to examine the issue.
If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.
If the latest kernel did not allow you to test to the issue (ex. you couldn't
boot into the OS) please make a comment in your report about this, and continue
to test the next most recent kernel version until you can test to the issue.
Once you've tested the upstream kernel, please comment on which kernel version
specifically you tested. If this issue is fixed in the mainline kernel, please
add the following tags by clicking on the yellow circle with a black pencil
icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ
Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.
If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ
Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.
Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.
Thank you for your understanding.

Title:
After update, error drm:intel_pipe_config_compare [i915] halts startup
Status in linux package in Ubuntu:
Incomplete
Bug description:
Today I installed pending updates on my machine and the restarted. On
restart, machine stops 5.5 seconds into boot process with the error
"[drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in
ips_enabled (expected 1, found 0)"
I can hop over to a tty login using ctrl-alt-F1 . The error appears
there too, but I am able to use the command line. I cannot start a
GUI environment. Sadly as a relative newcomer to Linux I do not know
enough to tell you if my problem is getting X to start or something
else entirely. Typing startx definitely does not help.
