Looking at /var/log/messages, seems like the ata4 and ata5 "SATA link
down (SStatus 0 SControl 300)" messages are normal.

ata5: SATA link down (SStatus 0 SControl 300)
Freeing unused kernel memory: 1016k freed
Write protecting the kernel read-only data: 12288k
Freeing unused kernel memory: 1964k freed

Failed to execute /init
Kernel panic - not syncing. No init Found.  Try passing init= option ...
