Well out of frustration 2 days ago i've grab a new SDCard and installed fresh (no backups or nothing.. plain vanilla) and after less than 24h the same problem occurs ... so i can scratch being a problem related to my previous card/installation. (i've downloaded the Win installer, flash the card, booted and updated... did not restore any of my previous setting or installed any add-on). :) :) |

RE: Kernel Panic randomly on 2 units
Did you already try to add "vm.min_free_kbytes" again?
The Pi1 had problems with kernel panic in combination with high network load. Adding this parameter fixed it. I've noticed that the parameter isn't set in the current Pi2 images. So perhaps give it a try: Add in "/etc/sysctl.conf" the parameter "vm.min_free_kbytes = 16384" or a higher value "vm.min_free_kbytes = 32768". Reboot. You could also try the newest Pi2 standard firmware: Terminal sync sync sudo wget -O /boot/fixup.dat https://github.com/Hexxeh/rpi-firmware/blob/master/fixup_x.dat?raw=true --no-check-certificate sync sudo wget -O /boot/start.elf https://github.com/Hexxeh/rpi-firmware/blob/master/start_x.elf?raw=true --no-check-certificate sync sync |

RE: Kernel Panic randomly on 2 units
I've tried the "vm.min_free_kbytes = 16384" setting on my RPi 1.
I hope avoiding my (multi) daily kernel panic freeze... |

RE: Kernel Panic randomly on 2 units
Please try changing the btrfs compression from lz4 to lzo compress=lzo in /boot/cmdline.txt

Thanks for your input But this is the 1st time i have this problem and since i was using the rPis for viewing an average bit rate of 15Mbit/s x.264 files without any issue prior to the latest Kernel update it might not be the situation you describe. Anyway i'm trying curly's idea and if it does not resolve the situation i'm going to try yours. (27th Mar, 2015 05:52 AM)Diako Wrote: I've tried the "vm.min_free_kbytes = 16384" setting on my RPi 1.

RE: Kernel Panic randomly on 2 units
I need someone with an RPi 2 to test this kernel, I'm hoping that the 3.18.y branch is simply buggy and 3.19.y is better.
https://db.tt/4xmGNDk2 Install by doing: Terminal sudo cp /boot/kernel.img /boot/kernel.good sudo dpkg -i linux-image-bcm2836_3.19.3+_armhf.deb I can't test it myself as I'm still out of town. Let me know whoever tests if you still have the same issues. @Exnor I had to target the RPi 2 since more folks seem to be having issues with it. I will update both when I return.

RE: Kernel Panic randomly on 2 units
Can you ask the same on github so all issue openers will test also?

Ok mate, but i don't have a Pi2 yet ... my situation occurs in 2 Pi 1 B models (one that i've even freshly installed without any addons ).

RE: Kernel Panic randomly on 2 units
@Exnor I will build a kernel for you to test now.
This is for RPi 1 https://db.tt/sNM5ty8M Install by doing: Terminal sudo cp /boot/kernel.img /boot/kernel.good sudo dpkg -i xbian-package-kernel_3.19.3+_armhf.deb Please read rules and do a search before you post! | FAQs | How to post log file? | Can't find an answer? Contact us. |

Now i've installed py RPi 2 with a stable version of xbian and of course i have the same problem than with my RPi 1. I can test your kernel but before i want to be sure that i can still update simply my xbian. Do you confirm it's ok ? |
