+Subject: Alpha Linux kernel fails with inconsistent kallsyms data
+Message-ID: <20080622201143.GA28262 at wavehammer.waldi.eu.org>
+
+Hi folks
+
+The build of the Alpha Linux kernel currently fails[1] with inconsistent
+kallsyms data. As I never saw that before, I thought about hardware
+problems. But in fact it is a bug in the Linux kernel.
+
+The end of the rodata section is marked with the "__end_rodata" symbol.
+This symbol have different aligning constraints than the inittext parts
+and therefor the start marked "_sinittext". Because of that the
+__end_rodata symbol shifts between < _sinittext and =3D=3D _sinittext. The
+later variant is seen as a code symbol and recorded in the kallsyms
+data.
+
+On fix would be to move the exception table a little bit and get some
+space between that two areas.
