Thanks a lot for the hint. Runnig the command reports:
	   *	IDLE_IMMEDIATE with UNLOAD

So, the is no kernel bug or drive issue. The only problem was just me
being stupid and reading the CFSSE word from the wrong ATA drive, by
placing the printk() in the wrong place.

The word value for the drive is actually 6123 in hex.

Funny fact: Seagate replied today to my ticked, stating that "This drive
does not support that feature."

Sorry for all the mess I've caused.

Regards,
