"0" here too. How can you not power off and just reboot? I see no reboot option, just "Switch off!".

Oh... terminal command. Got it

@Rushmore: I'm guessing this will mainly be in connection with the 'automatic reboot' problems some people are experiencing.

If you put a 50 in there (or maybe 51) and reboot, your system will hang like:

* (*) * * *

(picture those bootup dots or "balloons")

From the bug report:

The root cause appears to be that when we during Fremantle development switched to Upstart, it didn't anymore provide shutdown runlevel (runlevel is now a dummy script) so that the device would have been correctly powered off when max reboot count is reached (as it did earlier).

Also from report:

The updated version of getbootstate package & binary will have also some other improvements (in testing currently)

AFAICT "testing" in this case is internal Nokia testing, not Maemo's extras-testing.

Also, the bug report provides a temporary workaround:

To prevent that issue, power users could probably quickfix /sbin/preinit scriptwith something like this:

Code:

echo_g "Houston, we have a problem, powering off..."
+sleep 10
+poweroff
def_runlevel=0

Mine is at 0, and the file date reflects the time I last did a switch off via the power switch menu (no power cable connected). I guess that must be enough to reset it, then.

Why couldn't you just put

Code:

      echo 0 > /var/lib/dsme/boot_count
      ;;

in the currently empty stop) case in the /etc/init.d/zzinitdone file?

Looking at the getbootstate binary, there's the line:

Unexpected reset count %d exceeds maximum (%d)

which suggests that any reboot which doesn't set the boot_count to 0 is an "unexpected reset".

So maybe this is to avoid endless reboot cycles when something is seriously broken.

In that case, just making one of the normal init.d shutdown scripts set the count to 0 might be the right fix?

Edit: Or, maybe I've got the wrong end of the stick here.. does rebooting "normally" actually increment the count in this file at the next boot, or is it just kernel crashes that do this? If the latter, maybe something resetting the count in the zzinitdone start) case might be better, on the assumption that getting that far is far enough to count as a normal startup? Maybe I should leave this to actual Nokia devs Can't help being curious though!

Further edit: Ok, so if there's no shutdown runlevel, I guess the K00zzinitdone script in /etc/rc2.d/ isn't going to get invoked at shutdown. In which case pretty much all of the above can be ignored.
