I have a raid drive mounted here:

/data/

And certain directories like this one:

/data/somedir/somesubdir/

when I run

ls

w/ or w/o any flags, terminal doesn't return anything. It does not return an empty directory listing. It simply goes to the next line and sits there blank with no prompt coming up. I cannot CTRL-C out of it. I have to close this terminal instance and start over.

At first I thought it was something to do with the ls command, but its pointing to /bin/ls and I can ls other directories just fine.

Also, running this

find /data/somedir/somesubdir

immediately finds all the files just as expected.
