Priority: medium Bug ID: 65068 Assignee: dri-devel@lists.freedesktop.org Summary: AtomBIOS stuck after suspend/resume cycle whilst GPU turned off Severity: normal Classification: Unclassified OS: All Reporter: austin.lund@gmail.com Hardware: Other Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI
Created attachment 79884 --> https://bugs.freedesktop.org/attachment.cgi?id=79884&action=edit dmesg output when trying to switch back to radeon gpu.
I have two GPUs in my system:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6600M/6700M/7600M Series]
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
This is a macbookpro8,2 and hence the gmuxer is controlled by the apple-gmux driver.
If I suspend the system to ram whilst on the integrated gpu (i.e. the intel gpu), then after resume switch back to the radeon, I get a GPU hang.
I've attached the dmesg output that I get when I try this.
I'm using linux 3.10-rc3. I don't have X running when doing this (vgaswitcheroo won't allow this).
