rtapi_app: caught signal 11 - dumping core

I'm installing LinuxCNC on a new old computer.
I got toe error "caught signal 11 - dumping core".
I wonder what I am doing wrong?

Here is the report that was generated.

If you read this far, thank you very much!  What is the problem?
Thanks,
Marty

Thanks,
I will do disable secure boot and try again.
 

Progress, turned off secure boot and now LinuxCNC runs the demo.
I get one other error, "No parport registered at 0x378.  This is not always an error."
Computer has an aftermarket pci serial and parallel port card.
What's up with that?
Thanks,
marty

Here is the relevant section of the response to lspci -v

Yes you did type sudo lspci -v, I think I did too.
I put the address in the wizard for the parallel port.
I get the same no par port registered error but with the new address 0xe000.
Maybe I should get a new pci parallel port card.

That's with sudo for sure.
