Description Charles R. Anderson 2008-01-27 01:38:59 UTC

Description of problem:
hdparm doesn't report the value of Advanced power management level correctly. 
Instead it says "unknown setting" with a value of (0x8080).  This messes up
retrieving the value to save before suspending and restoring after resuming. 
See Bug #382061.

Version-Release number of selected component (if applicable):
7.7-1.fc8

How reproducible:
always

Steps to Reproduce:
1. hdparm -I /dev/sda

Actual results:

# hdparm -I /dev/sda | grep "Advanced power management level"
	Advanced power management level: unknown setting (0x8080)

Expected results:

The actual power management value, not "unknown setting"

Additional info:

Lenovo ThinkPad T61

Hello,
this seems to be fixed in current F10 rawhide (hdparm-8.6-1.fc9.x86_64):


[root@pok etc]# hdparm -B 255 /dev/sda

/dev/sda:
 setting Advanced Power Management level to disabled
[root@pok etc]# hdparm -I /dev/sda | grep "Advanced power management level"
	Advanced power management level: disabled
[root@pok etc]# hdparm -B 128 /dev/sda

/dev/sda:
 setting Advanced Power Management level to 0x80 (128)
[root@pok etc]# hdparm -I /dev/sda | grep "Advanced power management level"
	Advanced power management level: 128
[root@pok etc]# hdparm -B 192 /dev/sda

/dev/sda:
 setting Advanced Power Management level to 0xc0 (192)
[root@pok etc]# hdparm -I /dev/sda | grep "Advanced power management level"
	Advanced power management level: 192


So I think that this can be closed.

As the original reporter, re-confirming fixed in F10, hdparm-8.6-1.fc9.x86_64, Lenovo T61.
