Default Bug#585962: Hangs during boot unless radeon.modeset=0 is used

Package: linux-image-2.6.32-5-686
Version: 2.6.32-15

I had this problem on Squeeze after dist-upgrading with Synaptic 2010-06-13.
After a few seconds, the screen turns black with random horizontal gray
garbage, and the system hangs totally (keyboard leds included). After several
reboots, I've seen the last line on screen was related to drm. I've
experimented a little bit and found that passing "radeon.modeset=0" to the
kernel command line, the system works as before.

My system is based on an AMD Sempron 3200+ with a Sapphire X1300 graphics
card. FWIW I use the radeonhd driver on Xorg.

I suspect linux-image is not the right package for this report, since it
entered testing on 2010-06-11 and it ran fine for the subsequent two days.
Unfortunately I'm not skilled enough to be able to find a suitable package in
those entered on 2010-06-13. Since then, the problem shows even if I boot the
previous linux-image-2.6.32-3-686, the "rescue (single user) mode" does not
help.

Please let me know if I can help tracing this.
Thanks,
Salvo

You should use radeon instead.

Please try to get a kernel log (possibly using netconsole, see
Documentation/networking/netconsole.txt in the kernel tree).

Is firmware-linux installed on this system? Does adding
radeon.agpmode=-1 on the kernel command line help?

Cheers,
Julien
