    drm/i915: Disable the GM965 MSI errata workaround. · b60678a7
    Keith Packard authored
    Since applying the fix suggested by the errata (disabling MSI), we've had
    issues with interrupts being stuck on despite IIR being 0 on GM965 hardware.
    Most reporters of the issue have confirmed that turning MSI back on fixes
    things, and given the difficulties experienced in getting reliable MSI working
    on Linux, it's believable that the errata was about software issues and not
    actual hardware issues.
