iarp Posted September 23, 2015 Share Posted September 23, 2015 I have not been able to figure out what if anything is causing this. From what I can find online when searching for this, it seems to appear in topics about running unraid within an esxi image or something. This is on a standalone machine.

RobJ Posted September 23, 2015 Share Posted September 23, 2015 I see a few modules I don't recognize from standard unRAID systems. I have to ask, is this a custom kernel? If so, I suspect some part of the build was not configured correctly. The other thing I notice is that this is a rather old board, ASUS M2N-E with 2007 BIOS. That's probably one of the problematic nForce 4 boards. You can *try* to find a newer BIOS for it, but I would trash it, if it *is* one of the nForce 4 boards. Quote Link to comment
iarp Posted September 23, 2015 Author Share Posted September 23, 2015 Only plugin I had installed was Nerd Tools (http://lime-technology.com/forum/index.php?topic=37541.0). I have since removed it and am just running a reiserfsck --check on the drives as I saw that recommended in a bunch of other topics. Yes it's an older board. I suppose I should think about upgrading it. Other than Nerd Tools everything is 2 weeks fresh install of latest unraid 6. For now I've disabled VM's and removed all but the non-stock plugins. I'll see how tomorrow goes. Quote Link to comment
