I have now had four StorPort bug checks whilst the PC is doing background work overnight. WhoCrashed has identified all the four dumps as AMD RAID StorPort DRIVER_IRQL_NOT_LESS_OR_EQUAL (see attached dump files)
I attach also the Sysinfo printout

Shows the configuration of the two RAID devices
Drive C (system drive) is a Samsung NVMe SSD 960 Pro 512GB
Other devices

Is anyone able to point me to solution to stop this happening?
