Oops with 2.5.38

[Krishnakumar B]

Hi,

I am getting the following in my kernel logs with linux-2.5.38, which btw
is the first 2.5 kernel that I am able to boot into. It is a dual Pentium
III machine. I find this in the logs as soon as I log in. So I think that
this happens during boot-up. Kernel was compiled with the latest RedHat
RAWHIDE gcc-3.2 rpm.

The machine does not hang and I am able to use it fine. Please CC me on any
replies as I am not on this list.

-kitty.
