NMI received for unknown reason 30 on CPU 0. Hi all, on my IBM ThinkPad T23 I often get the following messages (together with a beep from the speaker): ------------------- Message from syslogd@...fan2 at Thu Aug 30 22:02:17 2007 ... stefan2 kernel: Uhhuh. NMI received for unknown reason 30 on CPU 0. Message from syslogd@...fan2 at Thu Aug 30 22:02:17 2007 ... stefan2 kernel: Do you have a strange power saving mode enabled? Message from syslogd@...fan2 at Thu Aug 30 22:02:17 2007 ... stefan2 kernel: Dazed and confused, but trying to continue stefan@...fan2:~$ Message from syslogd@...fan2 at Thu Aug 30 22:32:08 2007 ... stefan2 kernel: Do you have a strange power saving mode enabled? Message from syslogd@...fan2 at Thu Aug 30 22:32:08 2007 ... stefan2 kernel: Dazed and confused, but trying to continue Message from syslogd@...fan2 at Thu Aug 30 22:32:08 2007 ... stefan2 kernel: Uhhuh. NMI received for unknown reason 30 on CPU 0. ------------------ There seems to be no pattern in the "interarrival times" of this signal. Sometimes I get it about every 30 minutes, sometimes only once a day. It also doesn't depend on the kernel version. I now see this behaviour on this notebook for 3 years now. My current kernel version is 2.6.23-rc3 (plain vanilla kernel), Ubuntu Gutsy Gibbon. I have googled "Uhhuh. ..." and got exactly 3 (!) entries, but no solution. But it seems that this is somehow typical for some notebooks, especially ThinkPads. Any ideas ?
