V6.10 update > DMAR: ERROR: DMA PTE for vPFN 0xf2827 already set........

New V6.10 update and now I see a series of DMAR errors popping up in the monitor

 

 

I did a search and came across people suggesting doing a parity check. I just started one so we'll see what comes from that. I'll post diags if I keep seeing this pop up or if by request.

OK, parity check completed with 0 errors.

 

But, I have UnRaid set to send SNMP messages to my Synology log service. I am finding UnRaid sends a massive number of log messages all set as Log Severity of 'ERR'. I just received 376 log entries regarding....

Seeing the same thing.

I ran 6.10rc2 for a long time on an HP Microserver Gen8 without issues.

With the newer builds as well as 6.10.1 I'm seeing tons of these logs and my server will stop responding

randomly.

You must disable vt-d, v6.10.2 looks for that, there are stability issues, even some possible filesystem corruption if vt-d is enable with those servers, problem is believed to be caused by the NIC driver when vt-d is enable.

I just upgraded to 6.10.2 too and I see this error in the console.

I've had vt-d turned on since I've had this R710 server and have not had any stability issues or corruption as far as I can tell.

What else will disabling vt-d cause? I seem to recall turning it on for some reason. Maybe for GPU passthru?

 

 

[nraygun]

There's mention in the release notes of the tg3 module causing problems. So I followed the directions to blank it out (even though it appears my NIC uses the bnx2 driver).

I now only see 2 of the errors. And I think I need vt-d turned on for GPU passthru.

Am I good to go?

[aglyons]

I currently don't have any pass through enabled, heck I don't even have any VMs or Docker's installed yet. I also haven't come across any performance or system freezes. Everything seems to be working normal.

 

Hopefully I didn't just jinx myself lol

If you're seeing the above error you should disable vt-d, and it's a no brainer if you're not even using it.

[G3rman]

Disabling vt-d got rid of the errors for me.
