There are a number of modifications that have been suggested that people implement to address certain issues.

 

The ones I can find are:

- In /boot/armbianEnv.txt:

extraargs=libata.force=3.0

- If doing debugging, also add:

verbosity=7
console=serial
extraargs=earlyprintk ignore_loglevel

 

- In /boot/boot.cmd

regulator dev vdd_log
regulator value 930000
regulator dev vdd_center
regulator value 950000

and then run:

mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

 

- In /etc/default/cpufrequtils:

ENABLE=true
MIN_SPEED=408000
MAX_SPEED=1800000
GOVERNOR=ondemand

(or 1200000 instead of 1800000)

 

- And if using ZFS:

for disk in /sys/block/sd[a-e]/queue/scheduler; do echo none > $disk; done

 

 

I've gathered these from a variety of threads. Am I missing any here?

Armbian is a community driven open source project. Do you like to contribute your code?

Haven't monitored very closely the different issues, so it's not very clear to me what theses are fixing. If not too much trouble, could you add what they fix?

I guess what he is after is having this sorted on your summary by problem and fixes.

 

Also for the SATA issue the workaround that worked too is to exchange the SATA cabled. If someone wants to retain the hotplug connector I found something there that works

I think you are missing one zero on this value. Also, it's not changeable and by default it's 950000:

=> regulator dev vdd_log
dev: vdd_log @ vdd-log
=> regulator value
900000 uV
=> regulator dev vdd_center
dev: vdd_center @ DCDC_REG1
=> regulator value
950000 uV
=> regulator value 95000
Value exceeds regulator constraint limits 950000..950000 uV

Yup, fixed. Thank you. It may be the default and non-changeable, but it's a suggestion that has been put in from the Kobol team, which is why I included it.
