It seems that the EDID obtained from VGA monitor is incorrect.
Will you please open a new bug in
https://bugs.freedesktop.org/
and attach the output of dmesg, vbios.dump?
The vbios.dump can be obtained by using the following commands:
echo 1 > /sys/devices/pci0000:00/0000:00:02.0/rom
cat /sys/devices/pci0000:00/0000:00:02.0/rom > vbios.dump
echo 0 > /sys/devices/pci0000:00/0000:00:02.0/rom
Thanks.
