Priority: medium Bug ID: 69922 Assignee: dri-devel@lists.freedesktop.org Summary: Juniper (HD 5770): Hibernate partially broken since LInux kernel 3.10 Severity: normal Classification: Unclassified OS: Linux (All) Reporter: haeuslsc@fastmail.fm Hardware: x86-64 (AMD64) Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI

Created attachment 86790 --> https://bugs.freedesktop.org/attachment.cgi?id=86790&action=edit Log for failing (hybrid) suspend to disk

I built and installed the final version of 3.11 especially for testing the improvements of the radeon driver for my system.

However, I was no longer able to hibernate (suspend to disk) my system: the screen went blank, but fans were on full speed and power was not switched off. I have to reset the system and on reboot, there was no session to resume and the BIOS logged "A Hyper Transport sync flood error occurred on last boot. Press F1 to resume."

After that, I tried older kernel versions and figured out that suspend to disk works for me with 3.9.11, but no longer for kernel versions 3.10 and newer (tested with 3.11.1/3.12-rc2).

When I start the kernel with parameter 'nomodeset', suspend to disk works though (with DRM_RADEON_UMS activated).

Some details of my computer:
