Grub install broken after kernel update

Hello, We updated smp kernel on a Sun V20Z AMD Opteron Scsi device. After installation we tried grub-install /dev/sda and we got /sbin/grub-install: line 475: 4041 Segmentation fault [root@cict-009 ~]# uname -a Linux cict-009.toulouse.grid5000.fr 2.6.10-1.741_FC3smp #1 SMP Thu Jan 13 16:58:29 EST 2005 x86_64 x86_64 x86_64 GNU/Linux [root@cict-009 ~]# grub-install /dev/sda /sbin/grub-install: line 475: 4041 Segmentation fault $grub_shell --batch $no_floppy --device-map=$device_map >$log_file <<EOF root $root_drive setup $force_lba --stage2=$grubdir/stage2 --prefix=$grub_prefix $install_drive quit EOF Installation finished. No error reported. This is the contents of the device map /boot/grub/device.map. Check if this is correct or not. If any of the lines is incorrect, fix it and re-run the script `grub-install'. # this device map was generated by anaconda (fd0) /dev/fd0 (hd0) /dev/sda Any idea.
