Package: base
Severity: normal



-- System Information:
Debian Release: wheezy/sid
  APT prefers testing
  APT policy: (500, 'testing'), (500, 'stable'), (1, 'experimental')
Architecture: amd64 (x86_64)

Kernel: Linux 3.5.4-fb-aufs (SMP w/4 CPU cores)
Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8)
Shell: /bin/sh linked to /bin/dash

Lorsqu'on arrête la machine avec l'option HWCLOCKACCESS non précisé ou mise
à yes (c'est pareil), donc lorsque la machine effectue un

hwclock --systohc

juste avant de s'arrêter, la batterie perd sa charge. En fait la consommation
est à peu près celle d'une mise en veille.

Si on met l'option HWCLOCKACCESS=no (par exemple dans /etc/default/hwclock)
alors cette perte de charge n'a plus lieu. Un «sleep 1» juste après le
hwclock ne résoud pas le problème. Ce bug arrive avec les noyaux 3.0 -> 3.5.4.

À noter que ce bug n'a pas lieu sur une Ubuntu (il faudrait voir si cette
option est par défaut sur Ubuntu).

J'ai constaté la présence de ce bug sur tous les Toshiba et sur d'autres
machines. Voir à ce sujet

https://bugzilla.kernel.org/show_bug.cgi?id=47811

(je pensais ce bug lié au noyau auparavant).

English: Halt the computer with HWCLOCKACCESS not set or set to yes causes
battery to drain. (Consumption is about the same that when the computer
is in sleep mode). 
If we put HWCLOCKACCESS=yes in /etc/default/hwclock, then battery doesn't
drain off then. So doing

hwclock --systohc

before halt causes battery to drain. Put «sleep 1» after hwclock doesn't
change anything.
This happens on various computers but not with the Ubuntu distribution.
Look at https://bugzilla.kernel.org/show_bug.cgi?id=47811 for the first
bug report when I thought that it was an ACPI bug. (Now I think it's a
kernel bug in the gestion of RTC but may be I'm wrong).

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
