From: Torsten Kaiser on 11 Jul 2010 16:00 I just tried 2.6.35-rc4 to see, if a different bug is fixed, but noted that this kernel will only boot with radeon.modeset=0. If KMS is active the display turns off and the system is completely dead, not even SysRq+B is working. I build a new kernel with the radeon driver as a module and inserted it by hand via ssh. The ssh session, I was using has this output: ariolc drm # insmod ./drm_kms_helper.ko ariolc drm # insmod ttm/ttm.ko ariolc drm # insmod radeon/radeon.ko Segmentation fault ariolc drm # The final insmod segfaulted, the shell was displaying a new prompt, but not new input was possible. The system still reacted to ping and trying to create a new ssh connection resulted in a password prompt, but after entering the password no shell was provided. I tried SysRq+S, SysRq+U and SysRq+B, but not visible result. After a reboot I did not find any additional information in /var/log/messages. The effect was like the boot time failures with a builtin radeon driver: The display (attached to the VGA output) just turns off. But I had a second ssh connection open, doing tail -f /var/log/messages: Jul 11 21:30:23 ariolc kernel: [ 131.720470] [drm] radeon defaulting to kernel modesetting.

2010 -0400 drm/radeon/kms: fix bandwidth calculation when sideport is present Fixes fdo bug 27529: https://bugs.freedesktop.org/show_bug.cgi?id=27529 Reported-by: steckdenis(a)yahoo.fr Signed-off-by: Alex Deucher <alexdeucher(a)gmail.com> Signed-off-by: Dave Airlie <airlied(a)redhat.com> :040000 040000 2ff9114469e4569e1bebd659c9632c5b59bfc238 b0eb9a29c698da1eeb8289ba1180b8135a94ecd7 M drivers My system does not have any sideport memory. The other revisions before this did boot into the correct KMS mode, but I did not test X, because I'm using that system as a remote desktop server and only sometimes the fb text console to debug something that went wrong.
