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.
