I just bought a new radeon (1002:682c), to pair with my shiny new displayport monitor. It shows a display during through the BIOS POST, and grub, but when the kernel starts up, it's a coin toss whether or not I get anything. Sometimes it just goes straight into power saving.
When I do get something on the console, it continues to boot and then X starts up and puts it into power saving too. Trying to flip back to tty1 doesn't light up the display again.
I'm running On debian stable, with copied-by-hand verde_* firmware files from the linux-firmware git tree. Here's a log from the 4.0-rc2 kernel.
Any other info I can provide ?
