Problem installing on Dell Inspiron 3880

3880 is a completely generic desktop that I just purchased at Best Buy. When I try to install 2.8.2, I get the following error on boot:This is a bug that was fixed in the current Debian release, but not in Buster or Stretch. As far as I know, that means I can't run any version of the linuxcnc ISOs. But I could build a system from scratch with the iwlwifi fix and add linuxcnc. Unless someone has a better idea, that's my plan. Can someone tell me specifically which kernel is in the 2.8.2 iso? I know it's 4.19, but it helps to have the subversion as well.

Thanks, Joe


 

If you have recent hardware you will require a recent Linux Kernel.
I would probably go with Debian11 non-free (bullseye) and follow the install guide here:
www.qtpyvcp.com/install/bullseye.html

Alternatively, there is a long winded instruction set to install MXLinux on the forum here. They should both give you the same version of the kernel

Thanks. That would be 2.9 though, right? Is that likely to be stable enough?

Sell you could type:
git checkout 2.8 after cloning the repo to get V 2.8

well, 2.9 is a fail. Machine hangs randomly, including but not exclusively when running linuxcnc. Does anyone know when 2.9 will be released? My knowledge of linux seems inadequate to try anything until a supported solution arrives. I guess I could replace the dell, but its hard to imagine that there is something more vanilla out there.

Ok it the machine hangs when not running Linuxcnc it's not a Linuxcnc issue. Remember Linuxcnc is "just a program" running on Linux.

I would suggest to clean the inside of the machine from any dust, pay attention to the PSU and cpu cooler\heatsink\fan. Remove the ram, make sure the ram slots & ram module contacts are clean.

When you say "the machine hangs" does it become totally unresponsive or can you move the mouse, if you press CTR-ALT-F1 does it bring up a text terminal ?

Does CTRL-ALT_DELETE restart the system.

Hangs as in totally unresponsive to anything except the power cord.

I should add that linuxcnc is always running (machine is not used for anything else) but it will hang when I'm not using it, or using it.

Ok if it is a desktop model I still would recommend giving it a good clean.

Also I would recommend running a memory test.

Not being able to see the syslogs after the crash does make things a little difficult.

How did the machine cope with an extended latency test ?

Also the installed distro and kernel version would be a help as well.
