Comment 1 Danny Al-Gaaf 2005-08-09 11:34:32 UTC 
Holger: I think this is a bug in powersave. looks as powersave try to connect to 
HAL while HAL isn't ready.
Comment 2 Holger Macht 2005-08-09 11:43:01 UTC 
Yes, you ar e right. But what't the problem. I will remove the second error
message from getACAdapterStatus() and decrease severity from initHal from ERROR
to warning.

Tell me if there is another problem...
Comment 3 Andreas Jaeger 2005-08-10 19:54:12 UTC 
Is there a dependency of powersave on hal in the init scripts?  If it is, then
why is the start up script of hal finished before hal is ready?
Comment 4 Danny Al-Gaaf 2005-08-10 22:15:53 UTC 
Yes, there is a dependeny. If hal starts the init script is immediately back and 
return successful. HAL is started in this moment. This is the correct behavior. 

If hald starts, hal is "ready", but you can access the hal-service over DBUS 
first if hal ends the initial import of hardwareinformation and provides his 
services. 

To prevent such errors, you has to check if HAL provides his services over dbus 
currently or you must check the errorcode of the called function and retry 
later.
Comment 5 Holger Macht 2005-08-25 09:43:31 UTC 
reduced debug level and removed second error message
Comment 6 Holger Macht 2005-08-25 11:13:39 UTC 
This seems to happen on every boot. So we need a better solution.

Danny: How can I check if Hal is really ready? Is there a signal emitted over
dbus? Or any corresponing function?
Comment 7 Holger Macht 2005-08-25 12:46:51 UTC 
Ok, added check if hal service is registered with dbus. If not, proper warning
is thrown.
