The log simply ignores the drive altogether.

from the sound coming from the drive, it does seem that the drive
initially starts at boot, then stops.  After that stage the device
detection takes place.  as the item is a pata to sata converter
(emulated sata), it does not support hot plugging.

I also need to mention that this behavior (start-stop during boot) did
not happen on the 2.6.24 and I need to check the 2.6.27.  However the
device is detected by both of these kernels.

Hmmm...

Hmmm... Can you please apply the attached patch on top of it and
report the boot log?

here it is.  Let me know if you need other parts of the logs.

Ah.. okay, you need to change .hardreset to ATA_OP_NULL instead of
sata_std_hardreset.

On both 2.6.26 and 2.6.27 or just the 2.6.26?  The initial patch does
work on the 2.6.27

Thanks,

Tried replacing sata_std_hardreset with  ATA_OP_NULL but it didn't
work.  I'll add back the debug patch and post the results

Sorry for the delay

Here's the message with debug
