Boot fails with “driver pnp watchdog 0x1D5” after updating SSD firmware with sp136849.exe

[dggardner]

After updating SSD firmware with sp136849.exe the system Black Screened upon hibernation. Now it fails to boot displaying “driver pnp watchdog 0x1D5”. The SSD is INTEL HBRPEKNX0203AH="Intel Optane Memory H10 1TB". I suspect the update corrupted the firmware and the boot system no longer recognizes the disc. Is there any way to salvage this, ie. force a proper update flash?

• Select "Safe Mode" from the list to start Windows with a minimal set of drivers and services.
