Analysis of fails:

* igt@kms_async_flips@alternate-sync-async-flip@pipe-c-edp-1

This is a display test, unrelated to GuC log. The fail is due to some slowdown during display testing, from first look it seem to be test issue rather than Xe issue - the test is susceptible to slowdowns on CPU side.

* igt@xe_exec_system_allocator@eu-fault-4k-range-device

Also unrelated to GuC or the patch under test, but this is worrying.

During creation of buffer object from user space (`xe_bo_create_user()`), the kernel function `rb_insert_color()` was called on a NULL node.

Memory corruption within iommu domains referenced from within `struct device`? I hope we're not seeing this often.

Fails not related to series under test.
