woodrow-shen opened a new issue, #16808:
URL: https://github.com/apache/nuttx/issues/16808
### Description / Steps to reproduce the issue
This issue has occurs based on the modified config (rv-virt:pnsh) with
enabling SMP and protected mode for RISC-V qemu-rv for my purpose, and to reach
this, I have created the following patch:
```

```
After that, the build steps are
1. `./tools/configure.sh -l rv-virt:pnsh`
2. `make`
Then run the Nuttx:
```
qemu-system-riscv32 -semihosting -M virt,aclint=on -cpu rv32 -smp 2 -bios
none -kernel nuttx -nographic -device loader,file=nuttx_user
```
I've successfully got the prompt for NuttShell, but when `ostest` is
executed, somehow the test always fails at this point:
```

I'm not really digging to the root cause yet, but It seems there might have
race condition, and the issue would be eliminated if I change `waiter_action()`
by adding a delay:
```

At the same time, I found another
[issue](https://github.com/apache/nuttx/issues/16430) was reported which is
interested in. I wonder if anyone experiences the similar case before?
