Zwane reproduced this and when I compiled an identical kernel for him
it went away; the only difference wsa the compiler version.

i.e. this looks like a compiler issue of some kind.

Boszormenyi, Helge, could I get compiler versions? Zwane had

<zwane:#offtopic> gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
<zwane:#offtopic> Copyright (C) 2002 Free Software Foundation, Inc.
<zwane:#offtopic> This is free software; see the source for copying conditions
+.  There is NO
<zwane:#offtopic> warranty; not even for MERCHANTABILITY or FITNESS FOR A
+PARTICULAR PURPOSE.

so this looks like one of the offending compilers; the one I used that worked
was:

$ gcc --version
gcc (GCC) 3.3 (Debian)

Going over the disassemblies...
