Short answer - we don't know. Not enough info. What can you validate?
Going on the limited information provided, it may be a chipset error, a disk error, cable. I had a system once which couldn't drive the ide bus. When warm I would occasionally get on stdout
hda: not ready
hdb: not ready
and it would sit there, unable to shutdown or anything. Shutdown was, after all, on the disk. To judge by the times

hda: status timeout: status=0xd0 { Busy ),

This hda is a CD-ROM drive in my system, which dma is enable in the BIOS, but Kernel is disabling it and I want to disable Polling Media, So how can i update /etc/rc.local file to stop media polling.

Something in the back of my mind reminds me of a kernel option if you see a message like that.

Nearly everything is on the new drivers and sda, sdb, etc. Are you using the old driver for some reason? Bear in mind, also that cdroms are not as capable as hard disks; they don't have to be in most cases because of the read speed.
check
hdparm -I /dev/hda |less
