[ltp] A Fast /dev/sda is now a slow /dev/hda after later Fedora Kernel Upgrade

[Thomas Roessler]

Add "hda=3Dnoprobe" to your kernel command line in /etc/grub.conf,
like this:

title Fedora Core (2.6.13-1.1526_FC4)
        root (hd0,0)
        kernel /vmlinuz-2.6.13-1.1526_FC4 ro 			\
	       root=3D/dev/VolGroup00/LogVol00 rhgb quiet 	\
	       acpi_sleep=3Ds3_bios hda=3Dnoprobe
        initrd /initrd-2.6.13-1.1526_FC4.img
