The RX 6000 reports of 0.9.1 and 0.9.2 ran the completion callbacks of submissions the GPU never finished before any call returned VK_ERROR_DEVICE_LOST, although the completion thread polled the device first. Every value a queue hand-over or a host signal gives the submissions' timeline or the executed timeline is now noted before the signal (vk_sync_hw.h); the completion thread and the wait after a submit end the run when a timeline reads above that note. The first occlusion query found unwritten after its fence logs its submission, the submissions' values, both timelines' readings and the GPU breadcrumbs, and the lost device's report starts with the same line, so the next report shows whether the driver gave a value above the note.
