Some things for the testers to try, please: - mount the fs with ext2 with the no-buffer-head option. That means either: grub.conf: rootfstype=ext2 rootflags=nobh /etc/fstab: ext2 nobh - mount the fs with ext3 data=writeback, nobh grub.conf: rootfstype=ext3 rootflags=nobh,data=writeback (I hope this works) /etc/fstab: ext2 data=writeback,nobh if that still fails we can rule out buffer_head funnies. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
