Hey Mattias, In testing the RPi4 8Gb I've run into an interesting crash, not seen it on either a 4Gb or 2Gb mode, and I'm wondering if you're aware of it. It occurs with either the latest firmware or one from April 1st.
If I boot without a display connected, so just via serial console, I see the following crash. If I plug a display in (I've only tried the HDMI port next to the USB-C power it boots fine. I also don't see the crash on 2020.07, just the 2020 RCs, tried rc1 and rc5. I vaguely remember something similar to this in the past but I've not managed to find a reference yet.
