Can you attach a a broken dump as well (2.6.35 without the revert)? Also, please only provide dumps with module option modeset=1.

(In reply to comment #4) > Can you attach a a broken dump as well (2.6.35 without the revert)? Also, > please only provide dumps with module option modeset=1. No, on 2.6.35 without the revert always get a kernel panic or hard reboot and console not shows anything.
Comment 6 Albert Gall 2010-08-04 20:23:48 UTC
The first dump is good and have module option modeset=1 by default.

(In reply to comment #8) > Does booting with radeon.agpmode=-1 help? This might be related to bug 16581 > or bug 16574. Can you try the patches attached to those bugs? The option radeon.agpmode=-1 does not work and the patches do not solve the problem, the result is always the same as you know.

It is still a bug. I cannot boot with modeset=1 on DVI > port (not sure about VGA port status).

How much vram does your card actually have (not what's reported in dmesg)? Is it 128 MB or 256 MB? Also in comment 1, are you saying that vga works fine but dvi does not or that neither port works?

Also in comment 1, are you saying that vga works fine > but > dvi does not or that neither port works? I think my video card have 128MB of video ram, but I'm not really sure. Xorg.log show on UMS: [ 45.948] (--) RADEON(0): Mapped VideoRAM: 131072 kByte (128 bit DDR SDRAM) and lspci: 01:00.0 Region 0: Memory at e8000000 (32-bit, prefetchable) [size=128M] Region 1: I/O ports at c000 [size=256] Region 2: Memory at ff4f0000 (32-bit, non-prefetchable) [size=64K] Expansion ROM at ff4c0000 [disabled] [size=128K] 01:00.1 Region 0: Memory at e0000000 (32-bit, prefetchable) [size=128M] Region 1: Memory at ff4e0000 (32-bit, non-prefetchable) [size=64K] VGA to VGA work fine here but DVI to HDMI no.
