Is the firmware-amd-graphics / firmware-linux-nonfree package installed?
Yes, firmware is installed.
If yes, I'd suggest booting with
modprobe.blacklist=radeon
on the kernel command line (this will prevent the radeon kernel driver from getting loaded automatically). Then once the system is booted up, log in via SSH and run
sudo modprobe radeon
This way you should be able to capture dmesg output from loading the radeon driver.
That’s helpful. I did not get the dmesg output via SSH, but at the console. So the radeon driver loads the JUNIPER firmware, then the CYPRESS firmware and then hangs up.
The last 5 lines are like this:
firmware: direct-loading firmware radeon/JUNIPER_smc.bin
[drm] Internal thermal controller with fan control
[drm] radeon: dpm initialized
firmware: direct-loading firmware radeon/CYPRESS_uvd.bin
[drm] GART: num cpu pages 16384, num gpu pages 262144
And then it hangs up. Completely. :)
Thank you
