• 🈯️ G_RPI_UPDATE | 🈴 reboot kernel hang

Looks like some possible kernel teething issues.

Other notes:

• 500MHz RAM vs 450MHz on RPi 3

I'm getting some kind of kernel-related? error after issuing the reboot command where it will print a stack trace and freeze indefinitely. Not sure how to reproduce because it seems to happen randomly.

This is with the latest image on a Pi 3 B+.

[Fourdee]

@xmijo

Thanks for the report 👍
I can confirm we are able to replicate the same issues.

We are unsure the cause at the moment, however, learning towards possible kernel teething issues.

Quite a few syntax errors and 'command not found' in the boot scripts (/DietPi/dietpi/boot and /DietPi/dietpi/dietpi-cpu_set). Prints on every boot. Also, "gettext.sh: No such file or directory" on login.

I just edited my post, I see now that you guys are already aware of the wifi issues and the boot error messages seem to have disappeared after a re-image. Not sure what caused it in the first place but seems to work fine now. But if you were able to replicate it was probably not an isolated incident..

[MichaIng]

I also faced the missing gettext.sh message. Can investigate this evening.

@MichaIng

Can investigate this evening.

Hope this will not open a new case full of worms. :smile:

But: Why try wifi to start and Failed to try-restart ntp.service: Unit ntp.service not found. is still open, if you have spare time: https://github.com/Fourdee/DietPi/issues/1631#issuecomment-374240509

Reference, confirmed kernel dump/crash on Raspbian:

Seems a possible hardware issue, bad batch?

Has anyone else experienced kernel freezing (occasionally, not every time) when issuing the reboot command? Or did I also get a faulty unit

Unsure, however, i'll re-create our DietPi image using a RPi 3 (non-plus) just to be sure.

[Fourdee]

Image updated, same random instability issues for me.
1/5 reboots results in instant kernel dump. There is no consistency to it.

Cant be 100% sure, but I believe its an issue with the LAN chip. Always referenced in kernel dumps, and, happens during systemD ifdown of networking.

by this, can you please check wifi connection on RPi 3 (non-plus)?
Lack of hardware at the moment.

Can't get wifi working on RPI3

WiFi Problems (RPi 3)

I'm always getting this error:
null: error fetching interface information: device not found
when the system tries to connect to the WiFi.

@k-plan

Yep, just tested fine with v6.4 image on RPi 3 (non-plus).

[Zvezke]

From reading the posts above, I understand that there are various issues - but I also understand that the latest version of DietPi should be bootable on 3B+.
I've downloaded (DietPi_v6.0_RPi-ARMv6-Stretch.img), flashed and attempted to boot, but no.
Am I missing something?

[xmijo]

@Zvezke The latest version of DietPi is 6.4, not 6.0. Get the latest version from dietpi.com/download

[Zvezke]

@xmijo Thanks for replying, Xmijo. I only see one option to download - choosing 'Download image' - which automatically starts downloading 'DietPi_RPi-ARMv6-Stretch.7z'. Is there a way to choose v6.4?

[Fourdee]

@Zvezke

The version number is listed inside the .7z file. Download the file and you'll see its v6.4 :)

[Zvezke]

Oh, indeed it is. Sorry for the inconvenience.

[Fourdee]

WiFi solution is:

rfkill unblock wifi

Once run, WiFi + scan is now functional. Seems a permanent setting on subsequent reboots, once applied.

[Fourdee]

WiFi fixed: https://github.com/Fourdee/DietPi/commit/02e1f6bebb09a93c89e896fb7b606f25ee8952db

My device works fine with LAN disabled and WiFi use only. But, i will be sending it back due to fault:
https://github.com/Fourdee/DietPi/issues/1627#issuecomment-374669173

Completed.

[xmijo]

Great news that wifi is fixed

Is the kernel hang on reboot the reason for returning your device @Fourdee ? Do the issues persist on regular Rasbian, too? (Haven't got access to my device atm so cannot test it myself)
