Hi Herbert,

Possible.  I performed the bisect using a kernel configuration from the 
following instructions:

https://git.kernel.org/pub/scm/network/wireless/iwd.git/tree/doc/test-runner.txt#n55

In my case, I was using the User Mode Linux arch and testing locally using iwd's 
test runner.

# make ARCH=um olddefconfig
# make ARCH=um -j8

from iwd-git:
# tools/test-runner --kernel=<path to linux> --start=/bin/bash
<run the failing ell unit test.  Namely ell/unit/test-key and ell/unit/test-tls>

Here's my bisect log:
