Research direction
Start with the p2p_bandwidth command, the bandwidth.xclbin build output, and the SmartSSD environment described in the issue; compare the hardware run with the passing hw_emu and sw_emu runs. Done means the hardware application executes without the watchdog soft-lockup, using the documented platform and device configuration.

Description
Hi,
According to the VITIS ACCEL EXAMPLE Doc, I'm tring to test the code of P2P bandwidth example for my SmartSSD. However, I got a error when I run the command
./p2p_bandwidth -x ./build_dir.hw.xilinx_u2_gen3x4_xdma_gc_2_202110_1/bandwidth.xclbin -f ./data/sample.txt -p /dev/nvme0n1
the whole output of terminal is below:
WARNING: Ignoring -f option when -p options is set. -p has high precedence over -f.
Found Platform
Platform Name: Xilinx

kernel:[53262.306491] watchdog: BUG: soft lockup - CPU#81 stuck for 22s! [kworker/u224:8:1313]
Before executing the application, I run make all PLATFORM=xilinx_u2_gen3x4_xdma_gc_2_202110_1 TARGET=hw. There's no error in this process.
By the way, the hw_emu and sw_emu are all passed.
Here is my environment config:
OS: Ubuntu 20.04.6 LTS (GNU/Linux 5.4.0-155-generic x86_64)
XILINX XRT: version 2022.1
platform: xilinx_u2_gen3x4_xdma_gc_2_202110_1
device: SmartSSD
I passed the validation mentioned in the UG1382v1.3 by running sudo xbutil validate -d <bdf>
What should I do to run the application? Thanks!
