opengl error... conflicting with ethernet??

I just got a Dell optiplex GX280 comp at my office. I installed Mandriva (former mandrake). Everything is fine, except that, when i try to call any opengl function (even when i create an empty class that inherits QGLWidget), I get an error message as

Listening on Device /dev/pts/0
Message from syslogd@169-155 at Mon May 16 14:53:24 2005 ...
169-155 kernel: Disabling IRQ #16

I dont know what that means. But, after this thing pops up, my internet connection is gone... Does that mean anything :confused:

Can anyone please help me with this? I am trying to develop an applicatioin for viewing my output and am struck with this error. :(

169-155 kernel: Disabling IRQ #16
Perhaps your nic user IRQ 16 which is also used by your vga card. Run:

cat /proc/interrupts
to see if that's true.
You can either change the PCI slot of your nic (if it's not on-board), or change the IRQ from the BIOS.

this is what my /proc/interrupts look like...
0: 191620 IO-APIC-edge timer
2: 0 XT-PIC cascade
8: 3 IO-APIC-edge rtc
11: 0 IO-APIC-edge i915@pci:0000:00:02.0
14: 1432 IO-APIC-edge ide0
16: 3235 IO-APIC-level eth0
18: 0 IO-APIC-level uhci_hcd
20: 8373 IO-APIC-level libata
21: 3 IO-APIC-level uhci_hcd, ehci_hcd
22: 0 IO-APIC-level uhci_hcd
23: 15610 IO-APIC-level uhci_hcd, Intel ICH6
NMI: 0
LOC: 191634
ERR: 0
MIS: 0

I can see that 16 is associated with eth0. And, I am using the inbuilt graphics card, and no other thing is in PCI slot. Pls let me know what to do now. :(

hey, atlast , I found the problem...

seems i donot have hardware acceleration in my inbuilt card. So, i disabled the hardware acceleration and... thats it... its working perfectly fine now...

anyway, thanks for the support
