https://bugzilla.kernel.org/show_bug.cgi?id=34102 Summary: radeon drm/kms driver: please use suspend/hibernate notifiers for allocating memory in suspend routines Product: Drivers Version: 2.5 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx ReportedBy: Martin@xxxxxxxxxxxx Regression: Yes I have the issue that since switching to Radeon KMS neither in-kernel-suspend nor TuxOnIce - that I do not use anymore currently - hibernation aborts due to lack of free memory when I have more than just 2-3 applications open although I have 2 GB of RAM in my ThinkPad T42. For further details please see: Bug #30482 - try harder to free enough memory / improve image size autotuning According to Rafael "The problem is a consequence of bugs in device drivers that shouldn't allocate memory in their suspend/resume routines _at_ _all_. So, a more fundamental fix would be to modify drivers so that they use suspend/hibernate notifiers for allocating memory. IOW, you should complain to the developers of the drivers that cause problems to happen." (see https://bugzilla.kernel.org/show_bug.cgi?id=30482#c7) While I am not completely sure that it is the Radeon DRM/KMS driver allocating memory additionally memory during hibernation cycle having this issue since switching to KMS points at that.
