The SB600 RPR documentation does not mention what to do if SATA_BAR0+6
is no longer 0xA0 or 0xB0. It simply assumes that will never happen. My 500 GB Seagate Barracuda ST3500820AS triggers that corner case on the first init after poweron. The current code hangs forever with my drive. Fix this by rerunning the init sequence after SATA_BAR0+6 is no longer 0xA0 or 0xB0. Add support for SATA port 2-4 (Primary Slave, Secondary Master, Secondary Slave). If only the 2nd SATA port is connected and the hardware acts strangely (contrary to documentation), it will print the error message below and continue anyway. The official AMD asm code behaves the same way. SATA port 0 status = 0 No Primary Master SATA drive on Slot0 SATA port 1 status = 23 0x6=7f, 0x7=7f drive no longer selected after 0 ms, retrying init [8 repetitions] 0x6=7f, 0x7=7f drive no longer selected after 0 ms, retrying init Primary Slave device is not ready after 10 tries Activate and improve debug messages for SPEW log level. Fix some comments. New log messages look like this: PCI: 00:12.0 init sata_bar0=3020 sata_bar1=3060 sata_bar2=3030 sata_bar3=3070 sata_bar4=3000 sata_bar5=fc309000 SATA port 0 status = 23 0x6=a0, 0x7=80 drive detection not yet completed, waiting... 0x6=a0, 0x7=80 drive detection not yet completed, waiting... [... 281 repetitions ...] 0x6=0, 0x7=50 drive no longer selected after 2820 ms, retrying init drive detection done after 0 ms Primary Master device is ready after 2 tries SATA port 1 status = 23 drive detection done after 0 ms Primary Slave device is ready after 1 tries SATA port 2 status = 0 No Secondary Master SATA drive on Slot2 SATA port 3 status = 0 No Secondary Slave SATA drive on Slot3 With this patch, my Asus M2A-VM boots into Linux without problems.
