Hello, Try checking if your problems fall inbetween "patrol read enabled" and "patrol read disabled" (should be logged in messages). I've recently disabled "patrol reads" (mfiutil patrol disable) on an MFI controller, as it was causing instability on a VirtualBox host, when the patrol read happened at the same time as heavy IO. Good luck with it!
