This may point to the error being logged by use of smp_processor_id() in do_autoplug_timer(). Unfortunately without cpu autoplugging my system consumes about 8 W more when idle (or 1.50 € in electricity per months when running 24/7). I wonder whether these error messages can be savely ignored? David -- GnuPG public key: http://dvdkhlng.users.sourceforge.net/dk2.gpg Fingerprint: B63B 6AF2 4EEB F033 46F7 7F1D 935E 6F08 E457 205F
