Issue

• The kernel keeps logging timeout messages to the /var/log/messages file:

 kernel: hda: irq timeout: status=0xd0 
 kernel: hda: irq timeout: error=0x00
 kernel: hda: ATAPI reset complete
 kernel: VFS: busy inodes on changed media

or

kernel: ide-cd: cmd 0x3 timed out
kernel: hda: irq timeout: status=0xd0 { Busy }
kernel: ide: failed opcode was: unknown
kernel: hda: ATAPI reset complete

Note: the hda is a CD-ROM/DVD drive.
