I believe the issue is actually shown before, these are the li=
nes prior
to the error:

I believe the error is that the following function is trying to send a mess=
age
to a display, when the vga is not tied to any:
static int smu7_notify_smc_display(struct pp_hwmgr *hwmgr)
{
struct smu7_hwmgr *data =3D (struct smu7_hwmgr *)(hwmgr->backend=
);
if (hwmgr->feature_mask & PP_VBI_TIME_SUPPORT_MASK)
smum_send_msg_to_smc_with_parameter(hwmgr,
(PPSMC_Msg)PPSMC_MSG_SetVBITimeout,
data->frame_time_x2);
return (smum_send_msg_to_smc(hwmgr, (PPSMC_Msg)PPSMC_HasDisplay) =
=3D=3D 0)
? 0 : -EINVAL;
}
Is there any way to check if there is a display from hwmgr?
