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.
