 =======================


Reproducible: Sometimes

Steps to Reproduce:
1. launch X
2. do suspend from console (framebuffer enabled)
3. do resume
4. do switch to X from console
5. do switch to console OR (!) launch pppd (I'm not sure which action leads to bug)



Actual Results:  
Possible symptoms :
1. Sometimes my comp hangs when I do switch to console
2. In 1 of 3 cases when I do restart-hibernate-resume-hibernate FROM X, my comp hangs

Expected Results:  
no bug reporting from dmesg
