Comment 0 for bug 754711

Steps to reproduce:
- try to enter suspend mode (I used sudo pm-suspend)

Expected result:
- The system enters sleep mode and upon pressing the power switch, resumes successfully

Actual result:
- The system fails to enter sleep mode, although it continues to be usable (desktop is OK, I can keep typing and using the system). It just doesn't enter sleep mode.

The sequence of drivers preparing to enter sleep mode, and then resuming immediately afterwards, can be seen in the attached dmesg.
