It works now, I had in grub:
        linux /boot/vmlinuz-3.4.0 root=/dev/sda2 ro libahci.ignore_sss=1 quiet rootfstype=ext4 acpi_sleep=s3_bios usbcore.autosuspend=1 i915.i915_enable_rc6=1 rootdelay=1 fastboot resume=/dev/sdb2 resume2=/dev/sdb2 raid=noautodetect
and with
        multiboot /boot/xen.gz
        module /boot/vmlinuz-3.4.0 root=/dev/sda2 ro libahci.ignore_sss=1 quiet rootfstype=ext4 acpi_sleep=s3_bios usbcore.autosuspend=1 i915.i915_enable_rc6=1 rootdelay=1 fastboot resume=/dev/sdb2 resume2=/dev/sdb2 raid=noautodetect
it's ok. Thanks !
