But I can't repro the hung, and we have a timer at the hardness level
IIUC so IDK how this could "hang"?

Did you get a chance to build and test with the config file that I
have provided ?
I am using kselftest-merge configs for my daily CI system [1] on gitlab.

If you think the Kconfig is a test

I have not used the exact config, just a config with TLS=n.
I also have a different GCC version (11.1).
Unfortunately I don't have access to docker or podman on the machines
I'm using.

Naresh, is there any stack trace in the logs? Can you repro on Linus's
tree?

There is no stack trace print, it was only hung.

Can you check where the process is stuck and it's state?
/proc/$pid/stack and run that thru scripts/decode_stacktrace

I generally use remote devices. which have single serial connection only.
However, I will try your suggestions tomorrow and get back to you.

I couldn't reproduce this either - I have TLS=m

If you want to reproduce the same build or re-use the bzImage /
vmlinux / System.map
you may check the provided link [1].

Step to reproduce [1]:

# TuxMake supports the concept of runtimes.
# See https://docs.tuxmake.org/runtimes/, for that to work it requires
# that you install podman or docker on your system.
#
# To install tuxmake on your system globally:
# sudo pip3 install -U tuxmake
#
# See https://docs.tuxmake.org/ for complete documentation.
# Original tuxmake command with fragments listed below.

tuxmake --runtime podman --target-arch x86_64 --toolchain gcc-11

I only see build logs here, are there logs for the run?

Yes. Those are only build logs.
The test log is here but not very useful.
