Summary: kernel BUG when using nouveau
Product: xorg
Version: 7.4
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau
AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
ReportedBy: shiningxc-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org
QAContact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org
Loading nouveau drm module causes big kernel problems. Trying to load X always
results in hardlock.
If I blacklist nouveau drm module with the same kernel, it is perfectly stable.
