Thanks. Any ideas about why the load cycle count is so high and
increases so fast? I thought even -B 128 is a pretty standard value.
And would you recommend 254 or 255?
As to where to put the hdparm invocations, I suppose that writing an
"OnResume nn hdparm ..." directive in hibernate.conf will take care of
issuing it on wakeup, and setting all *_HD_POWERMGMT=254 in
laptop-mode.conf will take care of the AC power connect / disconnect
cases?
