You are right, apic is disabled...

The kernel is responsible for detecting the particular version of the processor available and the local apic to work on the machine. Look through the /var/log/messages to see whether the apic is available or being disable= d. This seemed to be disabled on a number of laptops. What is the information from /proc/cpu? Could check whether that can be= identified by the oprofile kernel module. Might tried using using an SMP kernel on the machine? -Will > > Thanks a lot > > > IBM Deutschland Entwicklung GmbH > Vorsitzender des Aufsichtsrats: Martin Jetter > Gesch=E4ftsf=FChrung: Herbert Kircher > Sitz der Gesellschaft: B=F6blingen > Registergericht: Amtsgericht Stuttgart, HRB 243294 > > > ---------------------------------------------------------------------= ---- > This SF.net email is sponsored by DB2 Express > Download DB2 Express C - the FREE version of DB2 express and take > control of your XML.
