This is on KVM? did you try acpi=off and it also looks like ecc isn’t on (not sure that’s an issue for rockstor but it is for other NAS distros).
It looks like there is a sound card error, could you remove the sound card or disable in BIOS and see if that improves? (do you need that sound card?) If it’s a VM you should be able to disable it on the VM.
What hypervisor are you using? What are the VM settings for Storage Driver, memory and BIOS?
I have this same issue just today on the latest update of rockstor, 1x 64GB SSD as boot drive. 10x 500MB configured as 1 for storage. Its just a test / play unit at work so not really any use for it right now.
I will leave it for the day and see if it “heals” itself as Suman said up there somewhere, its btfrs fixing the drives?
If not i will scrap it tomorrow and reinstall the OS
I tried booting without network cable, but it got stuck too.
But you are right instead of dialing nfs completely, I could remoint /root
and modify nfs-config.service to start after network is up. Which I did later.
