Hi, 

I believe that I detected a regression in the newest kernel 2.6.29 regarding 
Power Consumption during Sleep (S3 state).  As I reported before I had problems 
with resuming after sleep with the kernels before 2.6.29-rc6, so I didn't use 
Sleep anymore. Now that the resume issue is resolved, I started to use Sleep 
again and I noticed that my battery (full loaded before Sleep) was drained in 
maybe something like 5 or 6 hours. 

As I have a IBM Thinkpad with the famous Radeon chip, I validated if the 
radeonfb module was loaded and if the workaround was enabled. This was the 
case, so the question is where this power drain is coming from. 

I have now tested the kernel 2.6.27.13 and 2.6.29-rc6 with the same 
installation. This means that I am just rebooting to use the other kernel. What 
I have detected is that the 2.6.27.13 kernel behaves normally and with a normal 
low power consumption during sleep. I am using the famous sleep test script 
from www.thinkwiki.org 

This test script gives the following output :

Kernel-2.6.29-rc6  
Sun Mar  1 20:57:44 CET 2009
before: 33380 mWh
after: 31700 mWh
diff: -1680 mWh
seconds: 2056 sec
result: -2941 mW
Your model seems to be affected.


Kernel-2.6.27.13
Tue Mar  3 21:04:34 CET 2009
before: 31170 mWh
after: 30990 mWh
diff: -180 mWh
seconds: 1342 sec
result: -482 mW
Congratulations, your model seems NOT to be affected.

I will create a bug for this issue and there I will attach the corresponding 
dmesg and pm-suspend.log's for both kernels. But I just wanted to know if other 
Factory users are seeing the same behaviour. 

Regards

Raymond
