Mesa hm2/hm2_7i96s.0: error finishing read

One way to get a later kernel would be to upgrade to Debian 13 = Trixie = Testing
I think its on kernel 6.5. get the amd64 version, then try running andy's install script 
cdimage.debian.org/cdimage/weekly-builds/amd64/iso-cd/

Open "synaptic package manager" and search for or they are both there, it will also list linux headers just in case you need them for LinuxCNC dev.

Update...

New cable - no joy butwas worth a try - Thanks Tommy
PCW's IRQ affinity - no change in behavior, but thanks for the braiin-dead instructions.

Screenshot of the read times attached...  huge spikes.

Next step is a new kernel.

I've checked synaptics and the only kernel available with the bog-standard bookworm ISO install is 6.1.0-13.

Before I grease this thing and have a go with Trixie... image missing /media/kunena/emoticons/wassat.png

is there some other way to get the 6.5 kernel and patch?  I fumbled around last night and added 'testing' and 'unstable' debian repos through synaptics, but none of the newer kernels appeared in the search results.

Rod - where would I find Andy's install script?  Didn't see it in the announcements or computers/installing sub-forums.

You are welcomed, always.

Did you mind the spaces, there are two spaces between - - in my post, not having those turns empty when searched in synaptic.

Yes of course, you can use the same stuff i posted to search debian and pkgs.org, :
packages.debian.org/bookworm-backports/a....1-rt-amd64/download

Tried 6.5, no joy. read error within 5 seconds of starting LCNC.

Next step is Trixie.
