Description Alexandre Oliva 2005-05-05 03:00:39 UTC
I've found these in /var/log/anaconda.syslog, after an `@Everything' kickstart
install over NFS on my Dell Inspiron 8000.  Although this is running on a i686
(PIII 1.0GHz), the kernel is the standard installer kernel, IIRC built for i586.

Apparently fixed in FC4-re0504.0 and today's rawhide.
