Comment 30 for bug 1070690

I've seen the same problem on my Dell M4700. However, it appears to fail intermittently. The last time I booted, the driver loaded without error, but the time before that it failed with the message below.

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) (prog-if 00 [VGA controller])
        Subsystem: Dell Device 053e
        Flags: bus master, fast devsel, latency 0, IRQ 46
        Memory at f6400000 (64-bit, non-prefetchable) [size=4M]
        Memory at d0000000 (64-bit, prefetchable) [size=256M]
        I/O ports at f000 [size=64]
        Expansion ROM at <unassigned> [disabled]
        Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit-
        Capabilities: [d0] Power Management version 2
        Capabilities: [a4] PCI Advanced Features
        Kernel driver in use: i915
        Kernel modules: i915

Here's what the error looked like when it failed:
