Random reboot and unable boot

The phone periodically restarts itself after a reboot is loaded only the second time. In the first boot it hangs after the splash NOKIA.

In the logs found this - /var/log/maemo-optify-boottime.log

As can be seen for the first time the phone for some reason can not mount a directory

I would be grateful for any ideas how to fix this

Re: Random reboot and unable boot

flash it with custom emmc, maybe, :)

This is an last, not the best option =)

Re: Random reboot and unable boot

I do not have the constantly restarting problems, but I have the same log file growing since my phone restarted itself once. It never happened again (the restarting), but the file /var/log/maemo-optify-boottime.log is adding a new record every boot:
2012-10-25 18:01:20 :: not enough free space in /home (need at least 200 MB free), quitting.
1+0 records in
1+0 records out
512 bytes (512B) copied, 1.222565 seconds, 418B/s

Any idea about which process is writting to that file in every boot of the phone?
Thanks.

Re: Random reboot and unable boot

Well, I have made some progress, but still need an expert help.

The script which is generating the log is /usr/sbin/maemo-optify-auto-opt.sh, which calls the function dfree inside /usr/sbin/maemo-optify-lib.sh. dfree function is as follows

Code:

dfree()  

 {  

   space=`/bin/busybox stat -ft /home | /bin/busybox awk '{print int($5*$9/(1024*1024)) }'`  

   [ $? -ne 0 ] && return 0  

   return $space  

 }

If you execute the command

Code:

stat -ft /home | awk '{print int($5*$9/(1024*1024)) }'

you get two integers, not only one, and the last one is 0. Indeed, I have made an script to see the value of the returned $space variable, and it is 0!!! I cannot understand why it happens only in the last days (maybe a change in the busybox stat command?) Any idea?

On the other hand, I do not know where the /usr/sbin/maemo-optify-auto-opt.sh is called from on every reboot.

Please, help.

Thanks a lot.

Re: Random reboot and unable boot

@ikerrg,

Very interesting analysis. I don't have /usr/sbin/maemo-optify-auto.sh (but I may have removed many Nokia packages). Could you please do "dpkg -S /usr/sbin/maemo-optify-auto.sh" to see from which package this thing is coming?

Furthermore, that way of checking space using stat seems quite broken.

$5 is the block size, but
$9 is the total number of inodes

so the dfree() function is mixing apples with bananas :)

It should either use df[*] or replace $9 with $8, which is the number "available blocks" ($9 is the number of "free blocks", don't know what the difference may be).

Plus I don't know why awk returns two values when multiplying. Seems that busybox is way beyond broken (I tested with latest busybox-power).
[*]

Code:

dfree()  

 {  

   space=`df -B 1 | tail -1 | awk '{ print $4 }' `  

   [ $? -ne 0 ] && return 0  

   return $space  

 }

Good luck.

PS: I do have (in my most "normal" N900) a /var/log/maemo-optify-boottime.log, last modified about 8 months ago. Nothing in the boot process seems to be touching it, so it must have come from some package that I have uninstalled.

Re: Random reboot and unable boot

Thanks reinob. You are always there!!

I have moved the question to a more specific new thread and I give you more details on it: http://talk.maemo.org/showthread.php?t=87765

Let's continue there!
