Bug Description

[Problem]
The i915 kernel module seems to dislike having other kernel modules using the GPU. In some cases i915 will do a GPU reset and fire off a "GPU locked up!" event. The reset is successful and i915 carries on normally, so the user doesn't notice anything unusual and there's no symptoms other than the error messages in the dmesg log. However, this is enough to trigger the apport GPU lockup reporting tool to pop up on a subsequent reboot and prompt the user to file a bug report.

Essentially, module-init-tools (and other plumbing layer packages) don't always ensure a clean handoff between the vesafb driver and the i915 driver. However, when you know that i915 is going to load properly, you don't really need vesafb anyway.

[Workarounds]
Use xdiagnose to disable the vesafb framebuffer driver.
Or add it to the kernel blacklist.
Or direct apport not to file bug reports for gpu lockups. [This is the step taken for the natty release]

[Original Report]
Happens at every login. Not sure what is actually failing because everything seems to work fine.

Basically a dupe of #752940 but this is a "single-gpu" case. We believe the i915 driver conflicts with the vesafb driver. Typically there are no overt symptoms but sometimes it causes permanent lockup.

You can work around this by disabling the vesafb driver from loading (the xdiagnose utility helps here). But if your system isn't locking up, these error messages are harmless and can be ignored.

module-init-tools does perhaps need some massaging to better avoid these conflicts. Refiling bug.

Since this bug has four duplicates, and one of the duplicates (bug 767341) is itself Confirmed, it seems that this bug should be marked Confirmed as well. Any objections?
