Robert,

I've inquired about this problem with Allen Martin at Nvidia, he had the 
following reply:

/--------SNIP---------------/
Hi Bruce, I did work on the Windows SATA driver for those chipsets, so 
I’m familiar with it. I’m not aware of any of any timing workarounds for 
any devices in the driver, but it’s certainly true that there are 
devices that have timing sensitivity, especially around the IDENTIFY 
command and it may inadvertently work with one driver and not another.

 From the bug reports it looks like it’s always timing out on a 
TEST_UNIT_READY command? I assume this is probably the first command 
sent down after IDENTIFY to check for presense of a CD in the drive? If 
so it’s likely the drive is locked up and any command at that point will 
fail. If you want to test out the theory about it being a timing issue, 
I would stick some udelay()s in the identify code path, both before and 
after starting the transfer to see if it makes any difference. Also do 
you know if the driver does a PHY reset when it resets the link? If not, 
you can try doing that by writing a 0 to SControl and then restoring it 
with the original value.

Hope this helps,

-Allen

Does this provide any actionable information? I've tried searching for 
the proper location to impliment these delays in the sata_nv.c and 
libata-eh.c files but admittedly, am in over my head.

Thanks
Bruce

Title:
  System fails to connect to iHOS-104 DVD drive with nvidia MCP61
  chipset.

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  The computer fails to connect to the LG iHOS-104 DVD drive.
  The drive is working, as it will boot the Windows installer.

  I have seen similar bugs posted on the internet for the past 5 years.
  Here's a thread that shows the problem fixed for the MCP55 chipset.

  http://www.gossamer-
  threads.com/lists/linux/kernel/1234502?do=post_view_threaded#1234502

  WORKAROUND: Use the DVD drive with a USB-SATA adapter.
