https://bugzilla.kernel.org/show_bug.cgi?id=80901 Bug ID: 80901 Summary: [radeon] loading corrupts lspci entry + unloading crashes kernel Product: Drivers Version: 2.5 Kernel Version: 3.16.0 Hardware: IA-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: amerryfellow@xxxxxxxxx Regression: No Created attachment 143901 --> https://bugzilla.kernel.org/attachment.cgi?id=143901&action=edit lspci w/ radeon Hi all. I've been searching the internet for quite a while now, but couldn't find any solution to my problem. I currently am on a laptop Dell Inspiron 15R SE, with a i7 3632QM cpu ( which embeds a i915 intel card ) and a discrete AMD/ATI Radeon HD 773M. I know this kind of hybrid graphics setup's support is getting better more recently, but I still am facing some problems with the open source driver. The main problem is that, I don't really know if ( with PRIME ) my card is working at all. This is because when I tried the tool radeontop, it couldn't find my card. This is due, I suspect, to the fact that whenever I load my "radeon" module, I think it messes up the device. This seems confirmed by the fact that I get a clean lspci -vvv when the module is unloaded, and a "unknown header type 7f" when the module is loaded. See attachments please. Also, it takes a few seconds to load the module itself, and when I unload it ( modprobe -r radeon ) it crashes my machine, right after a few seconds. The system log shows a dereference problem, but "live" I can only see the stack trace the kernel outputs and nothing more. Steps to Reproduce: modprobe radeon modprobe -r radeon Actual Results: Radeon's LSPCI entry is messed up and card is not recognized by tools. On unloading, crashes. Expected Results: Radeon's LSPCI entry is ok, radeon card is recognized and on unloading, nothing.
