stack_collision failed in ubuntu_qrt_collisions

[Bethany Jamison]

For Mantic lowlatency, in ubuntu_art_kernel_aslr_collisions the KernelASLCollisionsTest.test_stack_collision test failed with the warning "System python is too old, crash handling disabled". There isn't much else to indicate what caused this test to fail. This failure has happened before in 2023.10.30 cycle but wasn't hinted.

The test is actually failed with timeout:

I will give it a try to see what's going on.
