Hook overriding its configuration file, and a broken resume report

[J Epperson]

A question here, and a broken resume report.

In trying to track down why resume from suspend does not work on my HP
dv6-1030us, I notices an oddity in the suspend hooks/configuration.

99hd-apm-restore.hook says:

source /etc/pm-utils-hd-apm-restore.conf

HD_APM_DEVICES=""

which looks like it nulls out any HD_APM_DEVICES setting from
/etc/pm-utils-hd-apm-restore.conf, so why is the setting exampled in the
distributed file via commented line?

What happens with this laptop is that suspend appears to work from outside
appearances, but resume throws continuous scrolling errors on a text
console screen, and the resume never happens.  It's hard to capture the
error messages in that environment, but they include (all prefixed with
ata1: or ata2:):

serror: {DevExch}
SATA link down (sstatus 1 scontrol 300)
EH complete
exception Emask 0x10 SAct 0x0 Serr 0x4000000 action 0xe frozen
irg_stat connection 0x00000040 connection status changed

Here are the suspend log, the smartctl and hdparm info on the SATA drive,
and the lspci info on the SATA controller.  Other information cheerfully
furnished on request.
