Summary: "trying to bind memory to uninitialized GART" error at resume from suspend to memory Product: Drivers Version: 2.5 Kernel Version: 3.9.3 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@kernel-bugs.osdl.org ReportedBy: casteyde.christian@free.fr Regression: Yes

Acer Aspire 7750G Core i7-2630QM, 6Go AMD Radeon HD6650M, no Intel graphics Slackware64-current

Since kernel 3.9.x, my laptop cannot resume from suspend to memory with X completly frozen and no other way to switch off/restart.

My rc scripts save dmesg at shutdown so I managed to get the following kernel logs:

I've also got once a kernel crash but haven't managed to get the dmesg output. 3.8.x and previous kernels were perfectly stable. 3.9 crashes roughly 1 over 10 resumes.
