Bug 58901

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:

usb 1-1.4: reset high-speed USB device number 4 using ehci-pci
PM: resume of devices complete after 1013.038 msecs

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.
