Created attachment 62685 [details] two samples of the kernel log I get the attached traces with 3.5-rc1 after suspend/resume, sometimes. It doesn't always happen. Usually happens at least once in 10 suspend/resume cycles. The first trace seems non fatal, but the system locks up in the second one and needs to be rebooted.
Can you attach your dmesg from boot and xorg log? Also is this a regression? If so, can you bisect?
