I guess you mean ext3. I know no efs3, only efs (of SGI - partially
supported by linux), which IIRC isn't supported by grub.

You'll first have to describe with much more details what you do and
what happens.

If you cold boot into linux, then e.g. run /sbin/reboot, linux should
boot through the BIOS etc., which should show its own messages before
starting grub. So if it's not, it's a bug either in linux or in the
BIOS. Do other OSes reboot well?
