I suffered exactly the issue described in the forum thread. My system froze for about 16 seconds upon startx until the ata link was hard resetted.

/var/log/messages:

###

touch /etc/pm/power.d/harddrive solved the issue completely. 
Should we maybe create that file as a default while installing pm-utils?

Reproducible: Always

Steps to Reproduce:
1. maybe not reproduceable on every system
Actual Results:  
1. login procedure hangs until the ata link gets hard resetted. system is frozen dduring this period.

Expected Results:  
1. should not freeze

In fact it is enough to change these values in /usr/lib/pm-utils/power.d/harddrive:

 # Default values on AC
-DRIVE_POWER_MGMT_AC="${DRIVE_POWER_MGMT_AC:-254}"
-DRIVE_ACOUSTIC_MGMT_AC="${DRIVE_ACOUSTIC_MGMT_AC:-0}"
+DRIVE_POWER_MGMT_AC="${DRIVE_POWER_MGMT_AC:-255}"
+DRIVE_ACOUSTIC_MGMT_AC="${DRIVE_ACOUSTIC_MGMT_AC:-254}"

See,

The file isn't present anymore in 1.4.1-r6. Closing accordingly.
