    Severity: normal

    Hello,

    I have a computer with an Intel i3-9100 CPU, using the integrated graphics, no graphic session running, and a monitor plugged in to the DVI port.

    The following command executed upon startup:
    setterm --term linux --blank 1

    After one minute of console inactivity the monitor is actually suspended, and I get the following effect every ~20 seconds:

    # turbostat --interval 1 --show PkgWatt,CorWatt,Avg_MHz,Busy%,Bzy_MHz,IPC,IRQ,CoreTmp,PkgTmp,POLL,POLL%

    Nothing is seen in `top`. I can see a brief ~20 watt increase in power consuption reported by the UPS.

    There is no issue while the display is active.
    If the monitor is unplugged these spikes occur every 20 seconds, even if no blanking/suspend is enabled.
    As long as the monitor is plugged in, and the display is not suspended on the computer side, the issue doesn't occur even if the monitor is powered off.

    With the i915 driver blacklisted the display can not be suspended, it is only blanked. The CPU spikes do not occur at all, whether the display is active, blanked or unplugged.

    The behavior is the same with linux 6.1.85 from bookworm.
