Public bug reported:
Binary package hint: acpi-support
At first, hibernation aka. suspend to disk seems to work fine, but there
are a couple of weird issues not noticeable immediately that render it
dysfunctional:
#1 Keys Ctrl-Alt F1-F7 do not react at all anymore!
#2 The Caps-Lock key works in X, but the keyboard light does on toggle.
#3 Approximately three minutes after resume from disk (hibernation), my
external USB mouse stops working. It appears that all USB ports do not supply
power anymore. It worked seconds before. kern.log contains:

Unplugging/replugging doesn't help afterwards. USB seems dead.
The laptop's two internal touchpad and button-amid-keyboard mice continue to
work.
Despite the above issues, X seems mostly functional (some apps may hang sooner
or later). However, I could not create another session on vt8. Xorg.20.log says:
Fatal server error:
xf86OpenConsole: VT_WAITACTIVE failed: Interrupted system call
Suspend to RAM is not affected.
The machine is a HP Compaq nc6220 laptop, running Intrepid (updated from Hardy,
updated from Gutsy, all release versions, no beta) with the latest updates at
the time of writing.
Hibernation worked good enough (not perfect, it has other quirks) in Hardy.
