   I have only one machine which has I211 (Shuttle DS57U).
 When doing "sysctl -w hw.acpi.sleep.state=3", it doesn't enter
 S3 but completely do power down... I can't test with this machine...
 
   I verified that my own ICH8 and PCH2 machine back from suspend, so
 not all chips have this problem.
 
 So, please
 
   0) could you show me the full dmesg?
 
   1) Is the link LED up or down when the machine is suspended?
 
   3) Does your machine recover from suspend when power or sleep button
      pressed?
 
 I'll try to test on some other machines.
 
 Thanks in advance.
