Returning from suspend can be tricky. Could you please send a more detailed log with debug enabled? Also, please attach the dmesg log too, as this could be a driver issue.

That's likely a driver's bug. So, I'm closing the issue.

If you want, feel free to add here the dmesg, and I'll try to address it very likely via a Kernel patch.
