+ one annoying problem. Upon updating you ended up booting random kernel ... you boot in last updated kernel.

Bingo! That works Safe to add permanently?

Double checked. Not working for me.

Nope, that didn't help. Thanks.

You are hidden from here if you mean that? This works as expected, but you see yourself of course. Hints has to be rewritten or perhaps only enabled back. Since search work decently, we might not need to expose alternative that much, only as a optional, not as a "must use".

If you have an option to power via micro USB or via GPIO pins, than GPIO is suggested method.

No fix, downgrade / old versions = workaround.

It's a know bug to all boards featuring A31. Status: https://groups.google.com/forum/#!topic/linux-sunxi/L9oBoyj0MsA

OK. This is better and more simple solution: systemctl stop log2ram.service systemctl disable log2ram.service

Yes, I can confirm ramlog service is not working properly ... rsyncing on shutdown is not successful, while on demand works. Some services like Apache or Nginx won't start if log (directories) are missing. We need to figure out why is this so. On brief look everything looks normal ...

This problem is solvable on legacy u-boot + kernel by adding those two lines to boot.ini: # To update boot loader on your eMMC, uncomment, reboot into SD card mode with your eMMC attached and comment back when done # run copy_uboot_sd2emmc While on modern u-boot / kernel, this remain broken.

For RPi monitor you need to adjust template.

It worked for some time ... But the actual problem was that cron job (which also handle purging of this table) was running with too low interval. Well, this is now sorted out.

If nothing was changed on the system I would try using different cables / PSU. I assume you are powering thee board via micro USB connector, which is problematic by default.

Important data are at download page, more general in docs.armbian.com, the rest you can find by using search engine or Google powered site search.

Scripts are inside (kernel,u-boot, headers, ...) deb package(s).

I recreated indexes but no go. Now I empty this table and it works ... for now

Upgrade to 8 core and 8G memory seems to provide no change at all. I suspect problem with mySQL since when I click "online users", this happens: my.conf With this hardware it should be as smooth as this. Edit: This command is super slow query_time: 11.154960: SELECT count(*) FROM `armcore_sessions` AS `core_sessions` WHERE ( core_sessions.id IN(SELECT MAX(id) FROM `armcore_sessions` AS `s` WHERE s.running_time>1488722103 AND s.login_type!=3 GROUP BY `member_id`) OR ( core_sessions.member_id IS NULL AND core_sessions.login_type != 3 AND core_sessions.running_time > 1488722103) )

Booting process is set to serial console and HDMI screen by default. Some kernels doesn't understand that and they default it to serial console ... you can force this by adding console=display to /boot/armbianEnv.txt Random HDMI blanking can be due to bad power supply, cables or similar. Edit: Also try forcing display mode with h3-disp utility.

H3 Ubuntu Core is not Armbian so we can't help much. Where did you get it?

When you go back with version, patches might break. You will need to deal with that ... check output/debug/patching.log for details and fix patches. In case patches are not important for you, disable them. No other way.

@Blop Can you make a picture of PCB or provide Ethernet and Wireless chip details & PCB version number.
