NMI interrupt received

[pandi k]

Hi All,

We are using Fedora Core 7 with 2.6.21 kernel and facing a issue in booting.

We have our PCI device on PCI slot and getting below message when system is
booting

Uhhuh. NMI received for unknown reason a1 on CPU 0.
You have some hardware problem, likely on the PCI bus.
Dazed and confused, but trying to continue

what could be reason for above display ?

Thanks,
Pandi
