Describe the issue you are experiencing

Hello,

We have home Assistant OS running in a VM on Truenass, and we are getting sometimes this error and this means that we have to reboot the VM every 1 or 2 days.

hope some one has a solution because its not really practical because all our home automations are not working 24h/7

Thanks in advance

What operating system image do you use?

generic-aarch64 (Generic UEFI capable aarch64 systems)

What version of Home Assistant Operating System is installed?

6.1.63

Did you upgrade the Operating System.

Yes

Steps to reproduce the issue

We don't know where the problem is coming from we change the number of VM core, but no change.

Anything in the Supervisor logs that might be useful for us?

No problems In log

Anything in the Host logs that might be useful for us?

No problems In log

I have similar problem. Home Assistant OS is installed on Proxmox virtual environment on mini-pc.

I'm having similar issues on Home Assistant OS on VMWare Workstation Pro

[dankocrama]

Any update on this ?

[mwb9aa]

Maybe this link will help? I'm trying it now. Basically, in the virtual machine, I changed the chipset type to ICH9. On my old machine, I used the other chipset, but on my new machine, I may need the other chipset.

[dankocrama]

I will have a check thanks for the feedback 🚀🚀

@dankocrama did you solve the problem ? I started to have the same issue on my HA VM in Trunas Core. Every 2-3 days it would crash with the same error messages. Thank you

[baturinivan]

I have fixed by updating proxmox VM to latest kernel version.

[dankocrama]

@MomosX No I still have the problem

[MomosX]

same :(

[siw1973]

Still got the issue on VMWare Workstation 17. 0.0

[dankocrama]

Did someone find a solution?

[CristianGonzalezFernandez]

Same issue here :(

[dankocrama]

Moved to Truenas scale, and already running for 30days without any bug

[MomosX]

I was thinking of doing the upgrade to Scale also, but too scared that something will break and it will take me a long time to figure it out.

[github-actions]

There hasn't been any activity on this issue recently. To keep our backlog manageable we have to clean old issues, as many of them have already been resolved with the latest updates.
Please make sure to update to the latest Home Assistant OS version and check if that solves the issue. Let us know if that works for you by adding a comment 👍
This issue has now been marked as stale and will be closed if no further activity occurs. Thank you for your contributions.

Staying alive.....

Still broken on VMWare Workstation and need to reboot everything every 4-5 days.

seen after upgrade to HA OS 14.1. VM was unreachable over the network. previous version was OK. after a vm reset via virt-manager, it recovered. dumping what was on the console and my libvirt vm config here..

I solved this issue on VMWare Workstation by turning off the automatic snapshots. I saw someone post that and didn't expect it to work. No CPU errors in 2 weeks.

Thank you for this, however this is a good thing and a bad thing !

Good - VMWare Workstation HA instance over 24 hours no CPU errors
Bad - My lazy backup strategy is now trashed and I actually have to put some effort into a proper backup plan....

[johnwalk61]

Too funny. Hope it worked for you. Mine has been stable for days now, not a single console error.

Nice find, but I'd say it's really just a workaround. @johnwalk61 do you remember where you saw the post suggesting it?
