"ahcich1: ahci_ch_intr ERROR ..." is a bit paranoid error reporting 
temporary left for debugging. It is OK for CD without a disk, as some 
commands, such as "get capacity", return ATA error status in such case.

Concatenation issue is probably not a bug here, as many of CAM messages 
printed with several printfs each. So printf buffering unable to help 
with it.
