Got this error message on my server, diagnostics attached as instructed.

 

Any help appreciated.

 

Thanks.

It's happening early in the start-up of your server, when devices are being recognised and well before the array starts. It's USB-related - some device wanting a service that is not available, such as a DMA-capable transfer buffer. A TV tuner? Try unplugging it and see if the problem goes away.

 

Thanks John, yes I had a dvb USB tuner attached. I removed it and no longer getting the error.

 

Would the error have been because the dvb tuner has become faulty or stopped working.

This is before any drivers are loaded so it is a possibility but I really don't know for sure. If the device actually works then you might well be able to ignore the error. It's certainly worth trying it in a different USB socket to see if that makes a difference - perhaps a USB 3 socket, if you have one.
