This is the nnth topic on this: my N810 sometimes spontaneously reboots 2-3 times a week. The frequency was higher but since I removed
/usr/bin/metalayer-crawler
/etc/init.d/metalayer-crawler0
the reboot frequency lowered, It usually happens when the device has a network connection (3g over BT or Wifi).
These reboots are by design as I see in the folder /var/lib/dsme/stats there is a file called [32wd_to] which just contains the number of self-reboots since reflash and is increased at every self-reboot. So ther should be a process / service / daemon which initializes these reboots. When this self-reboot is a result of a crash or hang, the OS is unable to maintain a statistics file.

Is there really no one who knows which daemon this is ? Are there Maemo developers on this forum ?

You've seen this page I guess?

http://wiki.maemo.org/Troubleshooting_boot_issues

(Scroll to the bottom).

Can you paste here the contents of:
/proc/bootreason
/var/lib/dsme/stats/lifeguard_resets

I created the core-dumps folders on both the root dir and mmc2 root dir and see what happens.

Core dumps will probably not help you (without some serious effort), but the contents of /var/lib/dsme/stats/lifeguard_resets will at least tell you what was crashing.

The core dumps are not filled after a reboot, but the file /var/lib/dsme/stats/lifeguard_resets is not updated the last 4 reboots, only the tiny file 32wd_to. So the reboots are still a magic, but probably network related as they virtually always happen when the device is connected to a (Wifi or 3G) network, regardless which Wifi.

/var/lib/dsme/stats/lifeguard_resets
Code:
/usr/bin/metalayer-crawler -F :  172 *
/usr/sbin/ke-recv :  6 
/usr/bin/hildon-input-method  :  7 
/usr/sbin/icd2 -l0 : 1 
/usr/bin/hildon-desktop  : 1 
/usr/bin/clipboard-manager  :  3 
/usr/bin/esd : 1 
/usr/sbin/multimediad  : 1 
/usr/sbin/dsp_dld -p --disable-restart -c /lib/dsp/dsp_dld_avs.conf : 1 
/usr/sbin/gpsdriver : 1
Since I removed /usr/bin/metalayer-crawler this file is not updated anymore.


/proc/bootreason: EMPTY (0 b)
