I've updated the description with some troubleshooting steps.
Looking at some of the dupes, people are hitting this same assertion but
with different system configurations. I would suggest everyone follow
the troubleshooting steps first.
If toggling in BIOS does it, then there's not much we can do on the
software side, at least for Precise.
However, if blacklisting the incorrect kernel driver solves it and makes
Intel graphics stop crashing, that may be of interest to the kernel
team. Undupe your bug report and update it with your findings, and
we'll go from there.
** Description changed:
+ [Problem]
+ An assertion is hit in drm_intel_bufmgr_gem_init. We've had about thirty bug
reports with this error. X crashes with this stack trace:
+
+ __GI___assert_fail (assertion=0xb6f2df80 "0", file=0xb6f2e5ac
"../../intel/intel_bufmgr_gem.c", line=2783, function=0xb6f2ebb7
"drm_intel_bufmgr_gem_init") at assert.c:103
+ drm_intel_bufmgr_gem_init (fd=-1, batch_size=16384) at
../../intel/intel_bufmgr_gem.c:2783
+ intel_init_bufmgr (intel=0xb85cfe08) at ../../src/intel_driver.c:409
+
+ The assertion appears to be catching a condition where the pci id does
+ not match any known intel chip generation. Yet (in most cases),
+ Xorg.0.log shows the system is indeed running on INTEL.
+
+ However, the system has two video cards. Either it's a hybrid (such as
+ in this case), or it has an add-in card.
+
+ [Troubleshooting]
+ 1. Run `lspci -vn | grep VGA` and verify that it shows two video cards.
+
+ 2. Look in your /var/log/Xorg.0.log for mentions of which X driver is
+ being loaded. The lines look like this:
+
+ [ 16.675] (II) RADEON(0): blah blah
+
+ 3. Run `dmesg | grep drm`. The messages will talk about whatever kernel
+ driver it is loading up.
+
+ 4. If dmesg mentions anything about "nvidia" or "fglrx", you have the
+ proprietary video driver installed, and probably should uninstall and
+ purge it first.
+
+ 5. If it is discussing "nouveau" or "radeon", then the kernel is trying
+ to load the wrong driver. Do any one of the following:
+
+ a) For hybrid graphics: In BIOS look for a setting to disable the
+ second video card and use it.
+
+ b) Blacklist nouveau and/or radeon in your
+ /etc/modprobe.d/blacklist.conf
+
