I am using 20.05-rc2 version to test based on HNS3 NIC hardware,

fix crash on exit) and it is ok.
We had a fix in rc1 that is supposed to fix this.

Copying Anatoly and David H. too.
Yes, and also this fix:
https://git.dpdk.org/dpdk/commit/?id=f4d1e19c293dc95073614f630ea729cf0bfb57b7
It's part of rc2 as well. With the above two fixes, all problems with
quitting the app should have been fixed (and were fixed, according to
our testing).

So I understand those traces are for when it works.
What about the traces when it does not work?
Yes, supplying log "when it worked" is not helpful if the goal is to
figure out what went wrong :)
Can you get a backtrace to know where the process is stuck?
I think that it is entered the rte_exit and can not eixt
Thanks for reporting.
the log as follows when it not works:

Again, this looks like a pre-rc1 log. Please retest with latest rc2 code.
it can not exit and enter the shell window.
Thanks
