Hello everybody,

Running environment: X86 OS: Linux ThinkPad-W541 5.4.0-47-generic #51~18.04.1-Ubuntu SMP Sat Sep 5 14:35:50 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux; DISTRIB_ID=Ubuntu DISTRIB_RELEASE=18.04 DISTRIB_CODENAME=bionic DISTRIB_DESCRIPTION="Ubuntu 18.04.2 LTS"

Raspberry Pi 4 OS: Linux raspberrypi 5.4.59-v7l+ #1338 SMP Fri Aug 28 11:55:37 BST 2020 armv7l GNU/Linux Raspbian GNU/Linux 10 \n \l

gnuradio and uhd: GRC 3.9.0.0-git UHD_4.0.0.0

The attached flowgraph can run correctly on X86, but on Raspberry Pi 4 it runs wrong.

Would someone can help this？

Suspect the same as #3882, please reopen if not actually just performance-issues.
