Hi, Warm reset was not able to recover from a device crash so ath10k was falling back to cold reset which would occasionally hang the system or generate a data bus error with some device chips. Warm reset now works a lot more reliably (at least on my T430). It's able to recover from a "hard" simulate fw crash and some firmware asserts I've forced meaning it should recover in most cases without falling back to the cold reset. There's still one case of a crash warm reset is incapable to recover from: IOMMU faults (when supported and enabled and device tries to access non-DMA mapped host memory) trigger device crash and leave CE totally unresponsive before and after the warm reset.
