Hello, all I ported the AHCI suspend/resume patch at http://www.spinnaker.de/linux/c1320/sata-resume-2.6.16.5.patch to libata-dev #upstream [ef2824073fba9def3cf122e89cc485f66dd71f70]. This series of patches provide the support for AHCI suspend/resume. The patch works very well on Napa SDV in our lab. The original author of the patch contact me, please. We can add you to Signed-off-by. Your comments and bug report are welcome.
