Loading on Macbook Pro ends with error on radeon graphics

[jeromezooce]

Hello !

I made a successful installation of Debian 10.6 32 bits on my 2007 MacBook Pro "Core Duo" 2.16 GHz (T2600).
Debian version installed is: i386/iso-hybrid/debian-live-10.6.0-i386-gnome.iso.

After some fixing such as installing the firmware-linux-nonfree and firmware-amd-graphics packages, I now boot and get the following message:
"fb: switching to radeondrmfb from EFI VGA"

My understanding is that it is switching from the default/basic VGA to using the Radeon GPU, but fails.
Once this message displayed, the system is stuck.

What could I do to unblock the situation?

Details on hardware:
[*] MacBook Pro "Core Duo" 2.16 GHz includes an ATI Mobility Radeon X1600 graphics processor with 256 MB of GDDR3 video memory and dual-link DVI functionality
[*] lspci -nn says: [AMD/ATI] RV530/M56-P [Mobility Radeon X1600] [1002:71c5]


Any help or suggestion is greatly appreciated.

Did you try switching to a console (TTY) screen? Adding 2 (or 3, or 4) as a kernel command line parameter will stop the graphical display from starting. Once you have a console login you can check the kernel driver and logs.

Yes I tried that, this is the way I know system is stuck. No answer for Ctrl+alt+Fx (x being 2,3,4,..)
I used the TTY console to install firmware-nonfree previously. Here, it does not come out.

On this post, here an update.

With a late 2006 MBP and Radeon, there is a bug that is not on the driver.
The solution would be to recompile the kernel and it seems to me a complex process.
Here is the post that helps to understand.

I would need assistance on this if someone is happy to give support.
Thanks you
