I've just installed CentOS 6.4 on my desktop machine. Everytime I start my terminal I get these error messages and I can't figure out why. How can I trace the problem and fix it?

Message from syslogd@dan-p4 at Jan 16 18:52:50 ...
 kernel:do_IRQ: 0.115 No irq handler for vector (irq -1)
  • Which motherboard? dmidecode -t 2 – Runium Jan 16 '14 at 15:10
  • @Sukminder do you mean: sudo dmidecode -t 2? As w/o sudo, you will get the version of dmidecode, but with sudo, you will get a lot more info. – Kevdog777 Jan 16 '14 at 15:14
  • @Kevdog777: Yes, as privileged user / root. – Runium Jan 16 '14 at 15:18

  • Do you have a NVidia graphic card and did you use their kernel drivers? – Nils Jan 20 '14 at 11:46

This doesn't solve why you're getting these messages but to just suppress these messages you can use this command:

$ dmesg -n 1

Add this to your user's ~/.bashrc to make this change permanent. Ultimately it sounds like you have a feature enabled in your BIOS that is not either supported or not configured correctly. You can also try disabling unused features in your BIOS to try eliminating these messages permanently.
