No /dev/apex_0 device about gasket-driver HOT 5 OPEN

Did you check if secure boot is turned on?
mokutil --sb-state

If so, you need to create a key and sign the module yourself. As I'm a lazy fedora user getting frequent kernel updates, I just turned SB off and gave up on this stuff...

I have slightly more encouraging output from dmesg than @MrMEEE above:

root@pve:~# dmesg |grep apex
[   21.359736] apex 0000:65:00.0: enabling device (0140 -> 0142)
[   26.492924] apex 0000:65:00.0: Apex performance not throttled due to temperature
root@pve:~# dmesg |grep gasket
[   21.324419] gasket: module verification failed: signature and/or required key missing - tainting kernel

However, like them, I do not have any apex in /dev

@robertzaage I have checked the secure boot status and confirmed it is disabled via the command you provided.

I am experiencing the same issue on Proxmox kernel 6.5.11-8. This is very frustrating. I have spent a good few hours troubleshooting this today.

Has a solution been found?

Having the same issue with 6.5.13-5-pve kernel. Secure boot is confirmed to be disabled.
