Comment 32 for bug 340014

Note that the relevant fixes were to the pm-utils and laptop-mode-tools packages, not acpi-support; acpi-support had a gratuitous call to hdparm but only in a path that was unrelated to this bug.

Fixing pm-utils and laptop-mode-tools cut the number of back-to-back 'hdparm -B' calls on resume from 3 to 1. The power transition event from unplugging the power while suspended would add an extra 1 call (via gnome-power-manager+devkit-power), so this is a max 2 'hdparm -B' calls vs. 4 before.

Since the problem was only being reported in the case where hdparm -B was being called 4 times back-to-back, we are probably now safely below the threshold where we'll trigger this; but a quirk blacklist *can* be implemented, if this problem recurs.
