Interesting to note that both tests failed with the blitter. No hang, and breadcrumb write must have succeeded, but an equivalent STORE_DWORD to the user buffer did not. Still suspect TLB or the aliasing PD?, just a pity it didn't hang.
This failure has not been visible in Patchwork Intel GFX CI Testing during August. I propose this to be closed as Resolved + Worksforme. Please comment if you disagree.
I confirmed that this is working on our side also
