@Hans Debug log: I will be able to obtain a serial cable for debug next week. Meanwhile, is it possible to grab the kernel without a serial cable? What do you mean by saying "you may need to use the debug version to get useful info"? No sound after all modules are loaded. Nothing, the Sam4...

Hi all, I am currently unable to boot AmigaOS 4.1 Final Edition on my Sam460 using either HDMI or the DVI port after replacing the Radeon HD 4650 with a Radeon R7 250E single slot and low profile. All is working fine using the VGA port. The installed Radeon HD driver is the latest v2.7, that was pre...

Checked: works fine on my Sam460 with Radeon HD 4650.
Thanks!

Sam460ex-3.19.0-3.tar.gz

Checked. Works fine, but did not notice any difference from the last kernel 3.19 with firmware included.

@Spectre660 I was looking for our kernel DRM error ("radeon: ring 0 test failed (scratch(0x8504)=0xCAFEDEAD)") on Google, and it seems that we are not the only ones having such an error. See this guy with a Freescale P1022 CPU and a RadeonHD: https://community.freescale.com/thread/339022 I...

uImage3.19.0-8b This should work with Radeon HD4650/HD4670,HD5450/HD6350,HD6450,HD6570/HD6670,HD7750/HD7770. This one works great! The RadeonHD 4650 driver is correctly turned on straight after loading the kernel. Audio is also OK after adding my user to the "audio" group. Both the Envy 2...

@Spectre660

Almost forgot: no sound at all, neither with kernel 3.16.x, nor with 3.19.

The sound cards simply do not show up. Have an Envy 24HT.

Tried to force reload following your advice, but still sound cards do not appear to the system

@Spectre660 Finally installed Xubuntu 15.04 from your ISO, it works just fine. Had an error with your script at the end of the installation, so had to install manually the kernel and the menu.lst file. Tried the kernel 3.19 and works, no DRM as usual. Tried kernel 3.19 with firmware for 5450,6450,65...

@Spectre660

That's great!
Looking forward to try it out, together with Ubuntu 15.04.
Still I am away from home and Sam460, will let you know as soon as I re-install everything.

Great forum that "linuxppc-dev",
we may end up with a kernel with DRM support!!

@Spectre660

First of all thank you for keeping spending your time on Linux for the Sam460, it is really much appreciated!

About your last message I must say that I'm lost.
Do you think these commits you have reported might lead to a working DRM kernel?
