Looks like this is a problem that all the segments in vmlinux are not on page
aligned boundary. Most likely it should be fixed by my patch which is in Andi's
tree and in -mm.

According to the FC5 kernel changelog, this was fixed.

- Another day, another round of lockdep fixes.
- Align kernel data segment to page boundary. (#206863)

However, bug 206863 was opened against FC6, and the current FC5
kernel (kernel-2.6.18-1.2239.fc5.i686) still has the bug.

Sorry, I should have mentioned the latest kernel I had tried this on instead of
relying on the date of my post (Nov 13) to be an indication of which versions of
the kernel I was talking about.

2.6.18-1.2239.fc5smp has this bug.

[root@server1 ~]# uname -r
2.6.18-1.2239.fc5smp
[root@server1 ~]# /sbin/service kdump start
Base address: 125e880 is not page aligned
