casaroli opened a new issue, #15582:
URL: https://github.com/apache/nuttx/issues/15582
### Description / Steps to reproduce the issue
Hello,
I don't see anything wrong with the commit
61f0c97193e3adbb1eee07bb854799d35843f12e, however, it seems to have broken
sim_vpnkit.
I come up with a minimal example, that we can reproduce even without running
vpnkit.
When NuttX starts, it will try to reach vpnkit socket, and after some
timeout it will proceed to nsh:
## Build and run:
```sh
./tools/configure.sh -l sim:vpnkit
make
./nuttx
[... no output even after 10 seconds ...]
```
Running current master (118f8271038afe24732dfc4376fb63b72e039dba) gives no
output, and running on the debugger we can see the wd has expired:
```

## Expected result:
If we revert that commit, it works:
```sh
git revert --no-commit 61f0c97193e3adbb1eee07bb854799d35843f12e
make
./nuttx
[... after about 10 seconds ...]
NuttShell (NSH) NuttX-12.8.0
nsh>
```
I don't know how 61f0c97193e3adbb1eee07bb854799d35843f12e could affect
`sim_netdriver.c`, kthreads or kernel workqueues.
Can anyone please give us a clue?
Thank you!
