intel_adsp/ace40/nvl/sim: kernel.memory_protection.syscalls.timeslicing and kernel.memory_protection.syscalls.kyield tests failures

[ekurdybx]

Describe the bug

Tests kernel.memory_protection.syscalls.timeslicing and kernel.memory_protection.syscalls.kyield fail on intel_adsp/ace40/nvl/sim with unknown error message.

Possibly the same issue as this closed one: 100892

Regression

• This is a regression.

Steps to reproduce

west twister -p intel_adsp/ace40/nvl/sim -s kernel.memory_protection.syscalls.timeslicing
or
west build -p -b intel_adsp/ace40/nvl/sim tests/kernel/mem_protect/syscalls -T kernel.memory_protection.syscalls.timeslicing

west twister -p intel_adsp/ace40/nvl/sim -s kernel.memory_protection.syscalls.kyield
or
west build -p -b intel_adsp/ace40/nvl/sim tests/kernel/mem_protect/syscalls -T kernel.memory_protection.syscalls.kyield

Was not able to reproduce with commit cc53c73.

[ekurdybx]

Hi @dcpleung, I checked and the issue is still reproducing on our CI. The latest Zephyr version that got this issue: v4.4.0-rc1-284-g4e5cb31d32a6

[dcpleung]

I still haven't been able to reproduce the issue on my end using Zephyr main commit 75c9794. Both GCC (Zephyr SDK) and xt-clang worked fine on my end.

[ekurdybx]

The issue hasn't reproduced in CI for some time now, so I'm closing this bug.
