Hi list,
I've a problem with my system on CentOS 6.5 x86_64 on a workstation.

During utilizzation, after several hours after boot (6/7 hours) I get an 
error:

  Disabling IRQ #16

and after this seems be that 3d acceleration is unloaded.

This is a workstation with a dedicated vga (nvidia gt450) and 3 nics.
This problem started when I've plugged the third nic.
Without third nic all works very good.

from /proc/interrupt:

  16:        110        647      64858          0          0          0 
          0          0   IO-APIC-fasteoi   ehci_hcd:usb1, ahci, eth3, nvidia


I've tried to boot the system with irqpool without great results.
I've tried to change my new third gb nic with a fast ethernet 10/100, 
thinking it was broken but the problem still persists.

I've tried to replace my vga card with another, the problem still persists.

 From dmesg I get:

Disabling IRQ #16

I've inserted the third nic for channel bonding.

What I can try to avoid this error? It's an hardware problem on mobo?

Any hints will be good.

Thanks in advance.
