Probleme compilation noyau linux

Bonjour,

lors de la compilation du noyau 2.6.11 j'obtiens cette erreur:

CC arch/i386/kernel/process.o
{standard input}: Assembler messages:
{standard input}:790: Error: suffix or operands invalid for `mov'
{standard input}:791: Error: suffix or operands invalid for `mov'

{standard input}:1184: Error: suffix or operands invalid for `mov'
make[1]: *** [arch/i386/kernel/process.o] Error 1
make: *** [arch/i386/kernel] Error 2

et je ne vois pas du tout de quoi ca vient.

Quelqu'un aurait-il une idee?
