Looks like MESA bug. 7.7 hangs, 7.5 does not. 7.6 hangs too. Does booting with kernel parameter radeon.modeset=1 help? KMS was completely broken on this system last time I tried it (3D did not work at all). > --- Comment #5 from Ondrej Zary <linux@rainbow-software.org> 2010-04-06 02:30:29 PDT --- > KMS was completely broken on this system last time I tried it (3D did not work > at all). > Netconsole (http://www.kernel.org/doc/Documentation/networking/netconsole.txt) might let you capture some useful kernel messages just before freeze. If normal boot doesn't produce any useful information from the freeze booting with drm.debug=15 would give lots of debug information. That sounds like serious bug that should be fixed. Is there open bug report about your KMS problems? Created a bug report about KMS problems here: https://bugs.freedesktop.org/show_bug.cgi?id=27517 |
