Just saw this message pop up on my unraid machine, "Disabling IRQ #18". What does it mean? What would cause it?

IRQ18.zip

Not directly relevant to you as you're on version 5.x but I saw this on version 6.x when I was attempting to pass through PCI controllers that were on shared IRQs.

 

I have a post about it here;

Are you running anything beyond vanilla unRAID that might be addressing hardware?

I had this once on v5rc?? When I tried using an Asus e350 motherboard. Issue was that there was an IRQ conflict because hardware devices and PCI / pcie slots were shared. It worked ok for a while but as soon as the system was under load it would crash.  I contacted Asus about it but after a few things they suggested didn't work they just told me Linux wasn't supported, so I gave up trying to use it for unraid.

Heh, funny you mention that. I'm using an Asus E350 mobo. I don't know what changed that made this start to pop up fairly consistently now. I'm trying irqpoll, and so far it seems to have calmed things down. I've also had a problem trying to copy to the unraid machine where the process would lock up mid-transfer. That also seems to be cured - at least momentarily. We'll see how things go long term.

Yeah it was same with me. Idling it would be fine, but when doing transfers it would crash. At the time the realtek nic driver was an issue too.

Well thanks for the bad news - no seriously! Better me knowing this mobo doesn't play nice than spending more time tracking down odd behaviour. I traded out the mobo with a Asus P5EVM from another comp so we'll see how that goes. It's has a E3110 (E8400 equiv.) in it so more horsepower but I'm sure it's mostly just going up in heat. Oddly though this system is pretty much on par with the E350 system. Doing a transfer now so have one disk plus parity I'm sure working and 3 other drives idling but not spun down yet and it's pulling 88W. Not a power miser but a lot better than I was expecting. When I get some time I'll probably under volt / under clock to shave some more watts. This system only has 2GB of RAM though and I'm sure DDR2 cost way more than what it's worth, think that low RAM will be an issue?

The 2gig tam should be fine if you don't run plugins. If you do then it will depend on which plugins you are using.
