Comment 3 for bug 1470014

I get the same error, and I've found the cause of it on my system:
- /lib/udev/rules.d/85-hdparm.rules calls /lib/udev/hdparm for every sdX and shX drive
- /lib/udev/hdparm loads functions from /lib/hdparm/hdparm-functions
- When the 'hdparm_options' function is called it sets a default global APM policy
- Because I'm on AC power, with a stock /etc/hdparm.conf file, this results in -B 254 getting set.

While you can change the APM value via hdparm.conf, the -B switch is going to get set, no matter what. And not all of my drives support that. I understand why this is being done, but, we need the ability to disable it. My suggestion is another option in hdparm.conf, say "noapm" :)

In the meantime, because I actually wish to use hdparm.conf and easily see any errors on boot, I've edited:
 /lib/hdparm/hdparm-functions, mine was line 88, comment out 'hdparm_set_option -B254'
