Summary: Black screen and crash on r600 with radeon module not loaded Product: DRI Version: XOrg CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: kilobug@freesurf.fr
If the radeon kernel module isn't loaded, starting Xorg gives me a black screen and I need to do a hard reboot (reset).
I've a HD4650 radeon, so it's r600 driver. This didn't happen with my old Radeon 9250, but I did upgrade X and kernel at the same time (to have r600 support), so not sure if it's related to hardware or to more recent X.
I'm using Debian GNU/Linux with 64-bits kernel and 32-bits userland and :
- xserver-xorg-video-radeon version 1:6.13.0-2
- xserver-xorg version 1:7.5+6
- libgl1-mesa-dri version 7.8.1-1
- kernel 2.6.33-2-amd64

--- Comment #6 from Gael Le Mignot kilobug@freesurf.fr 2010-05-24 10:59:16 PDT --- I managed to get the logs using network (since without the radeon module, I have black screen and I get a system freeze whenever I try to switch to text console).
It seems that when I don't load the radeon module manually from /etc/modules, it gets loaded automatically later in the boot process, and Xorg isn't happy with that.
Maybe a timing issue ?

--- Comment #7 from Alex Deucher agd5f@yahoo.com 2010-05-24 11:13:58 PDT --- Are you trying to use ums rather than kms? You need to disable kms if you want to use ums. (boot with radeon.modeset=0). If you want to use kms, the drm must be loaded before starting X.

--- Comment #8 from Gael Le Mignot kilobug@freesurf.fr 2010-06-26 04:54:48 PDT --- Well, I understand KMS won't work without the radeon module loaded, but it shouldn't crash, it should give an error message. Starting X with KMS enabled but module not loaded should either fail with an error message or fallback to UMS, but it shouldn't freeze the computer.
The weird part is that even if I don't load the module, it gets loaded automatically when X starts, but I still have a crash.
It's not a major bug since manually loading radeon fixes it, but it's still annoying when you have a crash and not clear hint on how to fix it.
