[Erik de Castro Lopo]

Public bug reported:


Graphics device is detected as an i915

    [    9.002405] i915 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
    [    9.002413] i915 0000:00:02.0: setting latency timer to 64

X is working, but the dmesg output is being spammed with 52 messages
like this:
