mps3: kernel.memory_protection.syscalls.kyield: FAILED Timeout

[arikgreen]

Describe the bug

The test case test_syscall_switch_stress failed on:
kernel.memory_protection.syscalls.kyield on mps3/corstone300/fvp failed (Timeout)
kernel.memory_protection.syscalls.kyield on mps3/corstone310/fvp failed (Timeout)

To Reproduce

1. checkout repo to Zephyr version: 3cbeb66474d9
2. run command: west twister -p mps3/corstone300/fvp -s kernel.memory_protection.syscalls.kyield

@arikgreen thanks for reporting this issue, but I believe this is not RISC-V related. Changed to platform: ARM.

Hi @arikgreen, I wasn't able to reproduce the error but I have seen this in ci few times and it works on retry. To avoid this issue I can increase the timeout_multiplier for these boards but to be sure could you try running the tests with below command?
west twister -p mps3/corstone300/fvp --timeout-multiplier 3 -s kernel.memory_protection.syscalls.kyield
