IIRC the double "resume from disk" entries were also present in English
(since my last apt upgrade I am now localised in french so I can't quickly
check).

Here we have the problem ... is this a DELL D600 or C640 or some other of

I'll read it but not now since it is quite long!
My laptop is a Dell Inspiron 630m.

BTW, I collected the following data this morning (I can also provide excerpt
of /var/log/acpid and /var/log/messages if needed):
Booted at 06:49

Kpowersave > STR @ 06:57, Resume @ 07:02
ACPI events @06:57: LID #1 (close)
ACPI events @07:02: AC, LID #2 (open), BAT0...
It took more than 10 seconds before the screensaver offered me to login

Apr 20 07:02:47 localhost kernel: [4295482.344000] ATA: abnormal status 0x80
on port 0x1F7
Apr 20 07:02:47 localhost last message repeated 2 times
Apr 20 07:02:47 localhost kernel: [4295512.373000] ata1: slow completion

Apr 20 07:02:47 localhost kernel: [4295512.373000] ata1: dev 0 configured

Apr 20 07:02:47 localhost kernel: [4295512.701000] ata2: dev 0 configured
for UDMA/33

Kpowersave > STR @ 07:15, Resume @ 07:20
ACPI events @07:20: AC, LID #3 (close??), BAT0, LID #4 (open??), BAT0...
Resuming was much more quicker, maybe 2 seconds after I opened the lid.
Second "preparation of STR" seems also to be faster because it seems the
closed LID event is logged on resume. And I don't have the ATA abnormal
status.

Finally I also noticed that the sound is muted after every resume, even
though it is shown as not muted.

Thanks for your help
