    Reset to device, \Device\RaidPort0, was issued.


      I am using a SATA RAID0 array as disk cache for a video production application. While the application is rendering (writing and reading from the array), there is a randomly recurring problem that freezes the video application, the IRST-application and prevents the computer from restarting / shutting down normally. When this happens, the system log shows the following error repeated every 30 seconds until a hard restart is done:

      I have clean installed Windows and created the RAID0-array in the UEFI settings. The system boots UEFI without the legacy option ROM. IRST reports zero parity errors or blocks with media errors. I have also extensively tested all connected drives for errors with several other tools. IRST controls write-cache buffer flushing. All power options are on high performance – I even made the ACHI Link power management settings visible from the registry to confirm they are correct. The system temperature stays low enough.

      The RAID array is fast, as it should, and sometimes works days on end before the error manifests itself again – it happens way too often to ignore, though. The system does not have any other issues. Can you please help me?
