Description Manuel Ullmann 2013-07-22 17:51:51 UTC

On the current LiveDVD-20121221, X freezes for my system, which is RS780M (AMD Radeon HD3200 mobile). The screen is black with big white lines. Magic sysrq is not working (well, sysrq+e added another line); getting to console is impossible. Booting with nox is working, so radeondrmfb works and I'm dropped to tty. A workaround is to use the gentoo-nofb kernel, but I'm missing the full screen resolution. However X starts this way.

Reproducible: Always

Steps to Reproduce:
1. Start LiveDVD with default options on a system with RS780M.
2. Wait until X is started.

Actual Results:  
X start freezes most likely kernel (e.g. sysrq is not working)

Expected Results:  
X should start in full screen resolution and don't freeze the kernel.

I searched the kernel bugzilla for similar bugs, but there are none (closed or open), where the freeze is at X start and radeondrmfb is working. I think 3.6.8 was stable once and I had no issues in december on my hard drive-Gentoo. So I'm dropping this to you guys ;-). I will test this on other radeon machines and report back. I think emerge --info is irrelevant, as you should know, how it is configured on your LiveDVD. I checked the iso before burning, but I have found a wallpaper, which seems to be broken. I'll attach it. Could be a sign for a damaged iso or a not well checked LiveDVD-iso ;-).

It seems that the most installed image viewers refuse to open the wallpaper, but gpicview and kde file selection dialog display it. According to gwenview it has corrupted metadata.

On a desktop PC with Trinity APU the LiveDVD shows the 4 Tux logos and basically does nothing for some time. The initial loading is quite short there is no output until the DVD begins to load and the screen changes to a corrupted image. At least SysRq works. So no framebuffer on APUs. I might test eventually another PC with Trinity APU.

The other Trinity is behaving the same. It gets to the Gentoo splash screen before freezing and replacing it by corrupted screen. Probably the low IO load at the beginning is the keymap selector.

I don't believe this affects any of the last few livedvd releases, please reopen if it does
