this error is an expected error, but the test it will stop at there, and fail with timeout.

Environment (please complete the following information):

• OS: Fedora32
• Toolchain: zephyr-sdk-0.11.4
• Commit ID: 6aa16e0

I cannot replicate this 'fail and timeout'. The test suite PASSes for me on up2 at that revision 6aa16e0. (I do not have a flash script, so I used USB boot media method with grub and zephyr.strip.)
issue_30306_up2_tests_kernel_mem_protect_userspace.txt

the same timeout issue with #30307

[jenmwms]

Closing this, it is now part of cluster in #30573
