+1 So this is the one I’d be most concerned about [1]. xe_exec_system_allocator is our SVM test, which does almost all the ridiculous things possible in user space to stress SVM. It’s blowing up in the core MM—but the source of the bug could be anywhere (e.g., Xe SVM, GPU SVM, migrate device layer, or core MM). I’ll try to help when I have bandwidth.
