Test crashes/failures on Ubuntu 24.04 with an AMD 6800 GPU

[johnzupin]

On Ubuntu 24.04.1, using an AMD 6800 GPU with the mesa version 24.0.9, the following tests crash/fail. This was seen with VVL at v1.3.300-16-g9d934c925.

Crashes:

• PositiveRayTracing.StridedDeviceAddressRegion

Failures:

• PositiveDescriptors.CopyAccelerationStructureMutableDescriptors
• PositiveSyncObject.ExternalSemaphore

LunarG's tcubumes6 CI node has Ubuntu 24.04.1 installed if needed.

Ran these with RADV Mesa 24.3.0 on Ubuntu 24.04

• PositiveRayTracing.StridedDeviceAddressRegion (even with Validation turned off) takes 10 seconds to run... not sure what is going on there
• PositiveDescriptors.CopyAccelerationStructureMutableDescriptors will be fixed in layers: Check vkGetDescriptorSetLayoutSupport #7609
• PositiveSyncObject.ExternalSemaphore - This one just takes forever and almost feel it is deadlock/timeout

actually PositiveShaderObject.TaskMeshShadersDraw takes down my entire system and makes me re-login my session everytime I try re-running it... that seems like a bug somewhere
