Description Garry Forsgren 2005-12-20 21:30:56 UTC 
The powersave daemon reports warning messages when a processor is offlined.

To reproduce:
On a MP system execute the following command where ${D} is any cpu other than 0.
echo 0 > /sys/devices/system/cpu/cpu${D}/online

Then tail /var/log/messages to view warning message
Comment 1 Thomas Renninger 2005-12-21 12:25:16 UTC 
Oooops, this is urgently needed for SLES10 and needs proper/early testing -> increasing severity.
Holger, can you do that? Tell me if you need help or a machine to test.
Garry: Do we need hotpluggable CPUs to test that or can we reproduce this on a common MP system?
Comment 2 Holger Macht 2005-12-21 12:48:44 UTC 
I am able to reproduce it here on a dual core system. So I need no further machine to test and will care about.
Comment 3 Holger Macht 2005-12-21 12:52:25 UTC 
This bug identyfied another smaller issue. The callback for testing whether the machine should get throttled is even called if throttling is disabled. Will fix that too.
Comment 4 Holger Macht 2006-01-10 16:57:30 UTC 
Both issues fixed in svn.
