SATA ATAPI AHCI error messages?

["Gaston, Jason D" <jason.d.gaston@intel.com>]

Hello,

We are seeing the following error messages in dmesg with the 2.6.16-rc5
kernel.  I have also tried to apply the git10 patch and still see the
same errors.  This is seen using a Plextor PX-716SA or PX-712SA SATA
DVDRW drive when in AHCI mode.  I do not see this message when the SATA
controller is set to IDE mode, in the BIOS.  I have reproduced this
using Intel ICH6R, ICH7R and ICH8 SATA controllers.  I have
atapi_enabled=1 set in the libata-core.c file.  These error messages
continue to be repeatedly logged about every 2 seconds.  Can someone
tell me what is going on and if this will be addressed in the next RC
release of the 2.6.16 kernel?
