On boot while trying to initialize the CCP the system freezes for up to five seconds. At the end of this delay I see: Oct 17 13:05:08 localhost kernel: ccp 0000:09:00.1: enabling device (0000 -> 0002) Oct 17 13:05:08 localhost kernel: ccp 0000:09:00.1: ccp enabled Oct 17 13:05:08 localhost kernel: ccp 0000:09:00.1: psp enabled Oct 17 19:05:13 localhost kernel: ccp 0000:09:00.1: sev command 0x4 timed out, disabling PSP Oct 17 13:05:13 localhost kernel: ccp 0000:09:00.1: SEV: failed to get status. Error: 0x0 Please remove the delay.
See if there's a new BIOS for your box and if so, update it. Also, pls upload dmesg and /proc/cpuinfo from the box. Thx.
Created attachment 285523 [details] /proc/cpuinfo
Created attachment 285525 [details] dmesg I have the latest BIOS version installed: https://bato.life/?l=ce4bf84e0482
My distro is Fedora 30 with all updates installed: $ rpm -q systemd systemd-241-12.git323cdf4.fc30.x86_64 # dnf update Fedora 30 - x86_64 - Updates Dependencies resolved. Nothing to do. Complete!
I could have asked ASUS to release a fixed BIOS to alleviate the issue but their support is absolutely atrocious and completely useless: for all the issues you encounter their advice is always the same: reset BIOS settings or RMA/replace your motherboard.
So in that dmesg I don't see that delay: Oct 17 13:52:31.651584 localhost kernel: ccp 0000:09:00.1: enabling device (0000 -> 0002) Oct 17 13:52:31.651774 localhost kernel: ccp 0000:09:00.1: ccp enabled Oct 17 13:52:31.652526 localhost kernel: ccp 0000:09:00.1: psp enabled Oct 17 13:52:36.821828 localhost kernel: ccp 0000:09:00.1: sev command 0x4 timed out, disabling PSP Oct 17 13:52:36.822384 localhost kernel: ccp 0000:09:00.1: SEV: failed to get status. Error: 0x0 You command times out very quickly. Are you saying the delay doesn't happen on every boot?
It happens on every boot. Only after I recompiled the kernel without the ccp module (could have simply blacklisted it but if it doesn't work why would I need it?) the delay disappeared. I also disabled the sp5100-tco module whose hardware looks not to be physically enabled but I doubt it had any effect on boot.

Doh, of course, it is late here and I must be blind. :-( Sorry.
We are just people and may get inattentive when we're tired. It's OK :-) If there's any other information I could provide I'd be glad to do so.

Thanks, it's finally working as expected in Linux 5.6.
