When booting 2.6.27-rc1 kernel on out intel SR1530HSH ( Quad core Xeon X3320)
Sata controller is ICH9r running in AHCI mode with newest bios.
After loading ahci driver backplane leds go amber which indicates a
non fatal error according to my intel resseller.
Everything works fine, there is no degradation in performance and
system boots up and runs correctly (for about 15 minutes after that we
went back to the old kernel).
I traced it to (introduced in 2.6.27-rc1):
