Hi, I upgraded my production HA system last night to the new 2025.9 release, and at the same second the CPU usage is now glued to 100% used CPU.
If I reboot HA, it goes back to 100% CPU-load after a minute.
The log files gives my no clues to why this happens.
Anyone else that has experienced this ?

Check with glances what uses the CPU.

Yes, I'm running on a Pi5 with a m.2 SSd.

#

The process "homeassistant" has been running at 400% CPU usage since the system has been booted. I don't think I should kill the homeassistant process.

Can you try pressing the / key or wherever it may be on a english keyboard to see the command's args?

#

Looks pretty much just like core though. I'd follow the core logs via ha core logs -v and see if something sticks out.
Afterwards try restarting core in safe mode via ha core restart --safe-mode and see if the problem persists.

More like this. For me it's the # key.

I just enabled debug mode and restarted. Will post shortly.

These integrations has been running in my system for years.

#

I have now removed the HASS_agent integration. And it seems to have made the CPU happy again.

#

Thanks for your help!

#

No problem.

#

And now the CPU is back att 200%. So I'll sarch for more integrations to delete...

Does it happen in safe mode too?

round scarab Sep 5, 2025, 8:29 AM

#

Don't know. I'll try.

#

So far, no more 100% CPU (in safe mode). But all integrations are not loaded. So nothing works anymore. There has to be a bad integration that hasn't been causing problems before 2025.9.
