Kernel panic - hard lockup

Hello all,

as I was calling smart.available(), I set up some logging which I piped to a file.
When I first restarted rockstor services, it logged SMART info for two HDD disks, but not for the NVMe SSD disk. I waited a bit and then killed the service.

I’ve tried again. This time I set up tail -f log in another tty session.
When trying to kill tail with CTRL-C, my kernel panicked. It didnt respond to keyboard as well.
I have taken a picture of the last few lines of the kernel panic before forcefully rebooting.

Kernel panicked again, this time at boot time and I took a picture as well. This time it seemed like a soft lockup, because the keys worked. The last line said something about “Fixing recursive fault but reboot is needed!”

So I rebooted again.
This time Rockstor is up and running.

My question is: where can I find the kernel panic logs?
/var/log/dmesg only holds the log of the latest, successful boot. There are no rotated dmesg files here.
/var/crash is empty.

Question #2 is finding out what happened.
Can you help? Should I talk to openSUSE folks?

This is a brand new PC. I have run some tests on RAM and disks before installing Rockstor, and no problems were found.

Thanks!

EDIT: I’m getting constant CPU stalling kernel-panic-like messages, mentions about postgres, gunicorn, so I am shutting the PC down now, because I need to go.

I wanna try booting without starting the rockstor services (which may cause this behaviour?). Is that possible?
