Hi,

I have a RedHat 9.0 box with a self compiled 2.6.7 kernel.

Today I had this error and a total lockup on the box. Before that (~6h
before I had another lockup, but no output to anywhere).

gcc, library files are all still from redhat 9, but there are a lot of
extra things compiled by hand or from fedora core libraries.
