  1. Next memory exception (page allocation failure) I found while doing rsync... This time I even disabled ram-log (50MB). ZRAM still @ 50%. During this failure the system did not freeze. So even if you have 512M, there might still be something broken with page allocation on kernels after 4.9.x!

  2. I changed the swappiness from 100 (=aggressive swapping) to 20. sysctl -w vm.swappiness=20 System seemed more responsive first but it got stuck again when installing php7.3 I set up the led to blink when accessing the sd card: echo "mmc0" > /sys/class/leds/orangepi\:red\:status/trigger It's fully on now. System only responds to pings. Guess the system is so busy that it doesn't even switch the LED.

  4. @5kft You could try to do some apt-get install commands. For example: apt-get install php7.3-fpm, apt-get install mosquitto Then purge again. And look if your swap gets used... Maybe this is only orange pi zero specific. But it is 99.99% NOT a hardware issue. It must be a software issue. Something in the kernel, or a driver is eating up memory or the swap usage isn't configured correctly.
  5. Next run - this time with zram = 50% After reboot: total used free shared buff/cache available Mem: 238Mi 72Mi 127Mi 0.0Ki 37Mi 159Mi Swap: 119Mi 9.0Mi 109Mi While "apt-get purge mosquitto" - it got stuck multiple times for a couple of minutes (=system unresponsive) The whole process took waaaaay too long for just purging a package. total used free shared buff/cache available Mem: 238Mi 94Mi 122Mi 0.0Ki 20Mi 137Mi Swap: 119Mi 79Mi 39Mi
  6. Setting CPU governor to performance (like described in this thread) does not seem to be a solution. I had a freeze again while running apt and while CPU governor was set to performance running @ 1.01 GHz. Memory before the test: total used free shared buff/cache available Mem: 238Mi 67Mi 132Mi 0.0Ki 38Mi 165Mi Swap: 59Mi 20Mi 38Mi Memory during the test (during freeze): total used free shared buff/cache available Mem: 238Mi 94Mi 127Mi 0B 16Mi 139Mi Swap: 59Mi 58Mi 0.0Ki
  7. I think it's a memory issue. I have tested again with kernel 5.4.7 (Armbian 19.11.6) I had a second ssh connection open this time running a "free -h" command every second. While running apt on the first ssh connection it showed me that free swap went down to 0 bytes, used: 59 Mi, total: 59 Mi I had changed zram config of armbian to use 25% instead of 50% memory. But I don't think that's the issue because others have the same problems without this change. And on kernel 4.19.x this memory issue does not seem to arise. Also the fact that users with 512M memory don't have stability issues is a hint that it's a memory issue.
  8. just to be precise: in my tests I've been using an orange pi zero - board rev 1.5 (the revision number is printed on the circuit board)
  9. @5kft It is possible to hook a serial console to the board, but what kind of outcome do you expect? I can even reproduce the freezing - all I have to do is to run a script that has some "apt install ..." calls with custom deb packages that I've built. Today it got stuck when configuring php7.3-cli (a dependency) for example. Then it said "process killed". The very same script runs without error on kernel 4.9.
  10. The causes for the system freezes are most probably NOT: the expansion board (I have none in use) the WiFi module (I have blacklisted xradio_wlan and use an ethernet connection) The causes could have to do with: *) the kernel *) system load / temperature / current draw / cpu frequency
  11. My Orange Pi Zero (256MB RAM) is also instable with recent kernels. I have tried: Armbian 20.08.3 with kernel 5.4.63 - custom built image: unexpected SSH disconnects, freezes (only ping works, but no ssh login), random problems with "apt install" - system freezes. "echo 0 > /sys/devices/system/cpu/cpu2/online" leads to kernel dumps or SSH freezes. Most recent custom armbian build with kernel 5.8.x: same as above Armbian 19.11.6 with kernel 5.4.8 - official image: same problems as above but putting cpu2 offline is working. Armbian 5.91 with kernel 4.19.59 - official image: everything working as expected. What I can eliminate as a source for these troubles is the SD card. I tried multiple SD cards (same SanDisk Ultra 16GB A1 Model). In my opinion there is something wrong with the kernel. The temperature readings (if correct) looked normal when installing packages ~50-60 degrees. Something in the armbian image broke after kernel 4.19.59. I am using a Xiaomi Mi5 Charger (rated for 2A) as power source, but I also have a programmable lab power supply available. I could try it with the lab power supply too but haven't done so.
  12. Ok, apparently it is not possible to reproduce old builds after more than ~ 1 month.
  13. I'm trying to add some extra packages and configuration changes to build v20.08. I did the following: git clone -b v20.08 https://github.com/armbian/build build-orange-pi-v20.08 cd build-orange-pi-v20.08 && git reset --hard 6e9b07e touch .ignore_changes ./compile.sh docker BRANCH=current BOARD=orangepizero KERNEL_ONLY=no KERNEL_CONFIGURE=no RELEASE=buster BUILD_DESKTOP=no CLEAN_LEVEL="" NO_APT_CACHER=yes The build ends with "ERROR in function compile_kernel [ compilation.sh:411 ]" When I clone the master without sticking to a revision, it's working fine. But I want to stick to an "official" build. How can this be done?
  14. Thank you. I'm in the build process right now. It seems to work, the process is installing a bunch of packages.
  15. I've attached the output.log It says: Displaying message: Checking for local cache buster-cli-armhf.e51...09a.tar.lz4 info Displaying message: searching on servers ... and then: Extracting ... So .. no, the new cache image is not made. How can I enforce this? output.log
