Installing 2.9 in Ubuntu 22.04/PREEMPT_RT was created by vedatech
My previous controller was an old dell running ubuntu 18.04 and linuxcnc-2.9pre. It just died. All of my machines run Ubuntu so I setup up a new asus z790-a/i9 computer with ubuntu 22.04lts running the core:
Linux control1 5.15.0-1034-realtime #37-Ubuntu SMP PREEMPT_RT Wed Mar 1 20:50:08 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
I'm using the mesa 6i25 card from the old machine mounted in PCIe slot 2.
I built linuxcnc-2.9 from source and it starts up but when I try to load my old config it sees the card but can't map the memory.
I'm running in the RIP environment.
This is the error:

I ran this first in the shell:
cd /home/dave/work/linuxcnc-2.9/src
sudo make setuid
cd ..
. scripts/rip-environment

It appears the kernel is locked down. /var/log/dmesg shows
[ 0.000000] kernel: Kernel is locked down from EFI Secure Boot mode; see man kernel_lockdown.7

I disabled secure boot in the BIOS and rebooted - it will not boot.
Enabled secure boot again and it still will not boot! Black screen.
*@#%$ UEFI

Probably will have to reinstall with secure boot disabled.
That has become the first thing to disable on new PC's, follewed by disabling UEFI where possible or enabling CMS.

I reinstalled ubuntu 22.04 with secure boot disabled in the bios. Doing a disk image backup this time so I won't loose my configuration and installed packages. I haven't tested it with the card in the slot yet.

No need for disk imaging, just save the configs folder to a USB stick.
Granted you do not have some strange configuration, that is all you need as a backup.

Sorry, I haven't been watching this topic for awhile. Yes, I have been using it with the real machine and its working - mostly. I'm having a problem homing the W axis but I will start a new topic for that.
latency-test give Max Jitter of 8823/9225 while using a browser and some other apps.
