When I got the ASMedia ASM1061, I had a similar problem. 

ahci_cmd_complete channel 1 CMD 0x4c017 CI 0x0
ahci_cmd_done channel 1
wd1: IDENTIFY failed
wd1: unable to open device, error = 19
ahci_exec_command port 1 CI 0x0
ahci_cmd_start CI 0x0
ahcisata0 port 1 tbl 0xc5ecb000
ahcisata0 port 1 header 0xc5ec4400
ahci_cmd_complete channel 1 CMD 0x4c017 CI 0x0
ahci_cmd_done channel 1

This was solved by adding AHCI_P_IX_PSS to list of enabled interrupts.

I would suggest looking at what the status is when it timesout.
