Cannot change IRQ affinity: Permission denied

Ask Fedora
1

I keep seeing this on every start up and when my PC goes to sleep. This normal? I think there is something wrong with my PC as even on Windows my PC acted weird. It seems like on both Windows and Linux. My install starts to break itself after a month of using it. I just had to reinstall Fedora as YouTube videos were freezing up my entire OS and i wanted to try Gnome instead of KDE. I saw these same type of permission errors with IRQ on KDE. This point to a bad CPU?

I can confirm the error. I also see it on Fedora 42.

My computer sometimes freezes when it wakes up from sleep mode - Freezing user space processes failed · Issue #37590 · systemd/systemd · GitHub

I don’t know if these errors are related.

Neither do I, but I have the same symptoms : system freezing and these error messages.

On F43 with a nvidia rtx 4000

And there is a solution In RHEL 9.3 or later, "irqbalance: Cannot change IRQ 76 affinity: Input/output error " - Red Hat Customer Portal but Redhat does not allow us to have it.
