Comment 10 for bug 1385165

I made a "copy to image file" of Fedora 21 beta LiveDVD. This is what I saw when DVD started to spin:

ata5: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xe frozen
ata5: irq_stat 0x00000040, connection status changed
ata5: SError: { DevExch }
ata5: hard resetting link

ata5: SATA link down (SStatus 0 SControl 300)
ata5: EH complete

and this is what I saw when DVD stopped spinning:

ata5: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xe frozen
ata5: irq_stat 0x00000040, connection status changed
ata5: SError: { DevExch }
ata5: hard resetting link

ata5: SATA link down (SStatus 0 SControl 300)
ata5: EH complete

It looked as if the logs were triggered by the DVD-RW drive. Observation about media players triggering these logs remains valid, though.
