Version 2.8.2 Debian Buster PREEMPT-RT ISO Freezes

I installed kernel 5.10 as recommended by AndyP and that fixed my persistent freezing. I don't know if that would be appropriate but thought it may be worth mentioning.

I had noticed your thread and did think that your problem sounded a lot like mine. I tried following the initial link that was supplied to you, but it's now broken.

At this point installing kernel 5.10 sounds like a very good thing to try. The only other options on the table are a complete re-install (in the hope that something went slightly wrong last time) and acquiring another computer

Where should I start?

I'm far from being expert / proficient / confident in this matter but I was able to install a more recent kernel without needing to reinstall Linux, LinuxCNC etc and that did the trick. The kernel is only one part of Linux, albeit the very core! And it's not unique to LinuxCNC.

It looks as if 5.18 is the latest stable kernel now.  www.kernel.org/  I don't recall what I did but it looks as if I simply installed it from the 5.18 tarball or the "latest release" icon. Pretty sure I didn't use the patch.

Sadly I fear that I'm even further from being proficient....

And I'm definitely confused on one point. It looks to me as if the kernels available from www.kernel.org are regular Linux kernels. Surely installing one on these without applying a RT patch would leave one with a kernel that was not suitable for use with a real time application like LinuxCNC?

?? I get "Unable to locate package linux-image-5.10.0-9-rt-amd64"

I did execute sudo apt update first.

Sorry for being so thick.

bash: wget: command not found

I seem to be cursed!

OK - I am learning (slowly). wget installed....

The good news is that the install was successful;

john@Taig:~$ uname -a
Linux Taig 5.10.0-13-rt-amd64 #1 SMP PREEMPT_RT Debian 5.10.106-1 (2022-03-17) x86_64 GNU/Linux

The bad news is that when I tried running LinuxCNC it froze almost immediately.
