The problem appears to occur if I press tab multiple times while listing the external drive directory. Here's an illustration of what has occurred. In Console 1, I was trying to list the contents of a lower directory and pressed tab several times to get the listing of the next directory level. The console froze. If I open a new console and try to list media/john, it freezes. If I open a third console, and use strace, the output is below. It froze on the second strace command. strace output has been reduced to show only several of the first and last lines.
One other thing. This used to occur frequently, and I would do a reflash (NVidia Xavier) in order to reduce the frequency. But I read if you change the cable to the external hard drive, that would help. So, I have changed the cable, and switch hard drives, and added a powered (plug-in) USB 3.0 hub to connect the hard drive to. So, this problem doesn't occur often now. And now, I typically do a soft reboot in order to continue.
Here's details on the current problem.
Console 1
ls /media/john/My\ Passport/lower_dir <tab><tab><tab> #FROZEN, NO RESPONSE
Console 2
ls /media/john/ # FROZEN NO RESPONSE
Console 3 (Frozen on the second strace command)
