/var/log/messages when inserting the radeon kernel module with modeset=1
Thanks for reporting upstream. We'll follow that bug. If I can do something to make things advance, please, let me know. You could try the latest drm-next kernel from "airlied" on kernel.org [1], he's the DRM maintainer. Maybe the bug is already fixed there. And if not, upstream will ask you to test that kernel anyway... Thanks [1] http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git with branches "drm-next", "drm-linus", "drm-radeon-testing", etc. Tested again with Linux 2.6.33-rc4 : All quiet on the western front but a slight difference (my monitor's LED now blinks when the screen becomes blank). Joined a new log excerpt in the upstream report. Tested with 2.6.33-rc7, I still get a blank screen :-( Ping the upstream bug, that's where the fix is going to come from. Don't hesitate to reopen this bug once upstream fixes this issue. Closing upstream. Thanks A follow-up on this one : the problem is solved ! Simply upgrade the kernel to Linux 2.6.35 (-rc3 at this date), install the latest revision of x11-drivers/radeon-ucode and you should see a nice framebuffer with a lot of text inside :-) Also, note that if you don't use initramfs images, you *must* set 'radeon' as being a module (it requires to load several firmware files). Note : Blank screen on every releases prior to 2.6.35 |
