Hello everybody,

I purchased my N800 two weeks ago.
Since last week I am experiencing constant reboots on my N800 (i.e.: 1 hour = 3 reboots).
This reboots usually occurr while I am surfing the web or reading RSS. (Although I had one on the control panel, I was not surfing or reading RSS on the back)
When surfing the web I usually have just 1 window open.
And I am subscribed to 12 RSS

Bluetooth is disabled
Email is not configured
Presence is disabled

Programs installed: VNC and MediaStream
Programs installed and unistalled: GPE-Tools

What to do? I do not know anything about Linux. I come frome Mac

You should stay if you are a linux novice or expierenced.

If you are a novice, do a backup first. Clear out and reset the box. Do a reflash if you have to, but that is not a guarantee to stop the reboots. Put all your stuff back and it will remain stable until you add some more flakey software.

I have a heavily loaded 770 and a new and bricked N800. The N800 is going back to the depot for evaluation.

As for the reboots, the linux is rebooting because of memory or stack problems. Make sure you have a swap file enabled and you use a lot of cache for Opera and you will mininise those effects.

Thanks for your reply!!!

Forgot to mention,

Yes, I have extended the virtual memory to 128MB and the Opera Cache to 4096.

I have also configured to do not download images on the RSS Reader


BTW, at the end of my post, I said that I do not know anything about Linux. I come from Mac

I've had two reboots during the +two weeks I've had my N800. Both times it happened while it was sitting quietly (with the screen off) on the desk. But I believe the media player was active both times, not actually playing anything. I too suspect a memory full problem, but I have tried later to run a simple monitoring setup ('free'+'sleep' loop in the shell), with no memory leaks showing at all. Clearly I've been unable to set up the right conditions, and it happens so rarely so it's difficult to get to see it.

See http://maemo.org/maemowiki/ReportingRebootIssues

I had something which sounds similar: https://maemo.org/bugzilla/show_bug.cgi?id=976

Ok... update...:

I reflashed my unit with the same newest version (51-6) I had.... and so far... No problems at all.

I haven't installed any program, but I used the browser intensively (10 windows open with flash running on them...) and in the back I was reading RSS.

Let's cross the fingers

Thanks for your help!!

I have just spotted this happening today and added a report to the bug. Though from my output below, what does the star * mean alongside the dsp_dld?

cat /var/lib/dsme/stats/lifeguard_restarts
/usr/bin/osso_hss : 6
/usr/bin/esd : 6
/usr/sbin/dsp_dld -p --disable-restart -c /lib/dsp/dsp_dld_avs.conf : 10 *
/usr/bin/metalayer-crawler -F : 1
/usr/bin/hildon-input-method : 1
/usr/bin/osso-media-server : 2
/usr/bin/ias : 3

I'm fairly certain the asterisk indicates the individual process which triggered the lifeguard to restart the device.

for the record, I have been having the same problem multiple times, after flash and reflash when I was only web surfing and rss reading for a week. There is one time, that the system start continuous rebooting right after I update the rss feed. Well, after I have set it to dualboot, and built my own kernel and boot it off the 8GB SDHC card, I haven't had problem yet. Granted it was only about 3-4 days, but heck I haven't had that problem yet. This may be too early to call it, but it seem that rss data may have somewhat incompatible w/ the jffs2 compression algorithm, or there could be a bug in the jffs2.

Since that day, I just had 1 "spontaneous" reboot while updated my RSS channels.

BTW, What I am having now is a another problem:
Every day, I shut down the device at night (I press the shut down button, and select shut down)... and some days, when I wake up, the device is on. I do not understand!
