Boot error with dbus

[Lemoine Simon]

Hi everyone,

I'm using dbus (1.4.16) on an embedded system (pico-SAM9G45) and I have
troubles sometimes when my system boots.

Here is my test:
During about 8 hours my system restarts every 45 seconds (as a
robustness test). To stop the system the command halt is launched
automatically, then the power supply is switch off and switch on 5
seconds after.

Once in a hundred, the directory /etc/dbus-1 is wrongly mounted, so dbus
stops. Here is the result of ls command :

# ls -l /etc/
total 8356156
-rw-rw-r--    1 root     root             8 May  9  2012 TZ

-rw-rw-r--    1 root     root           224 May  9  2012 group
...

When I try to list the contents of /etc/dbus-1 I obtain this :
# ls /etc/dbus-1 
...
[   49.320000] mmcblk0p2: rw=0, want=133695488, limit=3635200

...

Apparently the directory is wrongly mounted, but I do not know why, and
why it's the only one like that.

Any idea is welcome.

Best regards,
Simon
