System freeze

[s47]

Please see: http://forum.xbian.org/thread-2789-post-27655.html#pid27655 I've haven't had any problems until recently updating. Seems to happen only when downloading torrents with transmission. Dmesg log: http://pastebin.com/ZLbC9tci Kodi log: http://pastebin.com/ggAhcfxg

Latest build. Kodi 14.2 Beta RPI B model. No overclocking. Sufficient power supply. 8 GB sandisk class 10. Wired ethernet. HDMI, 2 TB EXT4 drive connected.

Last news : almost 24 hours since the beginning of the last test and my rpi still runs.

To complete my test, i'm going to delete theses lines from /etc/rc.local : echo 08 > /sys/devices/platform/bcm2708_usb/regoffset echo 0x31 > /sys/devices/platform/bcm2708_usb/regvalue

Moreover, i'm going to reinstall the last version of xbian-kernel.

We'll see in 24 hours ^^

@f1vefour np, I can.

Just to comment, the way I see to quickly reproduce the issue is not the only way it happens. Sometimes it will freeze a few moments after I boot.

[Diak]

My RPi is still running so it seems the problem is solved with moving the .kodi directory. If the problem finally come back i will post here but for now thanks a lot for the solution ;)

I've installed a fresh install of XBian on my RPi Model B and unfortunately I have the same issue. At least once a day the whole system freezes and I have to reboot to use it again. Because it happens randomly I haven't been able to save dmesg or anything.

This happens also after I've added the code below to /etc/rc.local : echo 08 > /sys/devices/platform/bcm2708_usb/regoffset echo 0x31 > /sys/devices/platform/bcm2708_usb/regvalue

Have you addedd before or after "exit 0"? Should be before check if you have the right values with cat /sys/devices/platform/bcm2708_usb/regoffset cat /sys/devices/platform/bcm2708_usb/regvalue

[rolftimmerman]

Yes I've added it before the "exit 0":

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

echo 08 > /sys/devices/platform/bcm2708_usb/regoffset
echo 0x31 > /sys/devices/platform/bcm2708_usb/regvalue

exit 0

This also works correctly:

root@xbian:/home/xbian# cat /sys/devices/platform/bcm2708_usb/regoffset
0x00000008
root@xbian:/home/xbian# cat /sys/devices/platform/bcm2708_usb/regvalue
Reg@0x000008 = 0x00000031

And my problem came back. Since Monday every day my RPi freezes....

I added again the two "echo" in /etc/rc.local but it seems hopeless...

[Diak]

And I as imagined the edition of rc.local doesn't change anything. Xbian is still very very unstable...

[CurlyMoo]

Even if you use the image we labeled stable?

[Diak]

I switched to the beta image because i had a big problem with the stable image which forced me to format and reinstall all from the beginning. I thought that the beta image couldn't be more unstable and dangerous than the stable one. And in fact i had less problem with this beta image...

Hopefully i will receive soon my RPi 2 and will be able to test my Xbian on it. If it's still unstable i will switch to another distrib.

Today xbian freezed after many weeks. I was using youtube plugin. I restarted and within 10 minutes it freezed again, while it was idle. The only thing I changed was removing of "elevator=noop" from cmdline.txt. Now I'm tring again with noop elevator and uptime is 4h

[Diak]

To keep you info, since my last post the RPi hasn't freezed again. I noticed that the last freezes happened when i was downloading a file so when there was a lot of I/O on the USB disk and ethernet.

[Diak]

And a new freeze/crash when nzbget was unpacking a download...

[Diak]

New behaviour, my RPi completely freezed but still respond to ping whereas before when it freezed even ping didn't work. XBian is going to make me crazy...

[rolftimmerman]

Is there a way to go back to the stable version without installing everything again? For instance downgrading the kernel and kodi to a specific version?

[CurlyMoo]

Standard apt functionality. A quick search on startpage or duckduckgo will give you the answer.

[rolftimmerman]

Yeah sorry wrong question, what I meant is what packages do I have to downgrade to get to the stable version again and which versions of the packages are used for the stable version?

[CurlyMoo]

We don't keep track of that. Images are automatically generated based on the latest debs in the stable repositories. Install the latest stable on a separate SD card and save the list of package versions. That would essentially be what i would have to do myself to get the answer.

[bellini666]

@RolfTimmerman you probably can probably use apt preferences for that.

Take a look at this post I've made regarding something alike I did on Debian.

The theory is the same, you just need to pin the stable repository instead of snapshots.debian.org with a priority of 1001.

[CurlyMoo]

XBian already uses these preferences for its own override packages.

[s47]

I'll just give you an update on my situation. My pi started freezing again and again up until I couldn't restart it anymore. Eventually I couldn't boot and I only had one red light indicating on the pi. Tried 3 different SD cards with different versions of Xbian but I just couldn't get it to boot. I think the card reader might have gone bad. I don't know if that has had anything to do with my problems mentioned above. Either way I have ordered a new rpi 2 and can't wait to try it out with xbian.

I have tried several power adapters, and the freeze even occurs with a 2.5A adapter. It can be easily reproduced (not every time, but nearly every time) with a "btrfs scrub start /" command. I will open an issue for this ASAP.

[f1vefour]

I successfully used btrfs scrub several times in a row trying to reproduce but it completed successfully each time.

[bellini666]

I have also been able to reproduce my issue with btrfs scrub start / in the first try (took ~4 sec for it to freeze).

[wlatendresse]

What are you running xbian on f1vefour?
