<pre>Card: Nvidia NVS295 with 2 DisplayPort connectors.
Problem: nouveau is spamming the kernel message, that it cant find the EDID of
not connected ports. Of course it cant, because there is no monitor connected
to that port.
When i connect the monitor to DisplayPort number 1, it writes, that it cant
find EDID on DisplayPort number 2. When i connect it to DisplayPort 2, it
writes that it cant find EDID of Display Port 1.
Linux kernel version: Kernel 4.19RC2 (its also there on older kernels)
Output when connected to DisplayPort 2 on kernel 4.19RC2 :
