Kernel panic - not syncing: hung_task: blocked tasks #8

Closed adrelanos closed 7 years ago

adrelanos commented 7 years ago

Currently testing http://s3-eu-central-1.amazonaws.com/ds9-eu/dci/images/stretch/armhf/netrunner-core/netrunner-core-20161213.1334-armhf.img.gz

Got this during sudo reboot.

kernel:[ 3123.957975@1] Kernel panic - not syncing: hung_task: blocked tasks

Does this get in the way of rebooting the device? I can reboot just fine here.

Rohan Garg:

Yes. I had to plug out the power cable.

shadeslayer commented 7 years ago

Could be because of the incorrectly built kernel, please try and upgrade as requested in the other thread and let me know if the problem still persists.

adrelanos commented 7 years ago

No more kernel panic.

journal did not work out of the box.

sudo journalctl -b1
Specifying boot ID has no effect, no persistent journal was found

Needed to apply this solution: http://askubuntu.com/a/858126/389275

mkdir -p /var/log/journal
systemd-tmpfiles --create --prefix /var/log/journal
systemctl restart systemd-journald

(Otherwise I couldn't have checked the shutdown log.)

Is journal intentionally disabled?

shadeslayer commented 7 years ago

Nope, should be enabled by default, but entirely possible that a busted kernel caused the journal to not be init'd?

adrelanos commented 7 years ago

No idea. Quite possibly a follow up issue indeed. Let's look out for this when a new image is released.

shadeslayer commented 7 years ago

The journal issue is a bug in Debian https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=717388

shadeslayer commented 7 years ago

I'm closing the bug since the reboot issue is fixed with the new kernel.
