Hi,

I'm new on FreeNAS, and I need your help.

I recently add this card on my NAS, but after adding this card, I have this error on the console of the NAS.
Before added this card, I didn't have any problem.

But now I have this error message which is printed on the console every seconde: Interrupt storm detected on "irq264:"; throttling interrupt source

Motherboard: MSI H110M PRO-VD https://fr.msi.com/Motherboard/H110M-PRO-VD/Specification
CPU: Intel® Core™ i5-7400 https://ark.intel.com/content/www/f...5-7400-processor-6m-cache-up-to-3-50-ghz.html

Thank you for your help.

Well, the first thing I would do is remove the card and, presumably, the interrupt storm will cease.

Then, if you search the forum here for "HBA" or "host bus adapter" you will find a lot of information on which add-on SATA port cards are proven to work well with FreeNAS and also many reports of failed attempts to use other add-on cards.

From the hardware section in "Resources" on the masthead find https://www.ixsystems.com/community...bas-and-why-cant-i-use-a-raid-controller.139/ to get you started on the road to more understanding.

Perhaps if you post in the French section someone can point you directly to a local vendor for one of the "good" cards. FYI, many of us buy used cards from ebay sellers. One I have used with satisfaction is The Art of the Server.

Hello, I'm late to the party I know, but hopefully my reply will matter to someone

I actually had this card for a while on a motherboard without any issue, no storm irq messages running a zfs on 6 drives
Then I changed the motherboard for another model and the same error as yours appeared.

I concluded that it's a hardware problem, either in the new motherboard or in the PCI sata card or both

I'm considering to remove the card because I have 8 sata slots on my new motherboard so I don't need this card anymore

I'd advise you to replace either your motherboard or your PCI sata card or both

Update: I just moved the PCI card from the x8 slot to the x4 slot and suddenly the messages went away
I don't know what exactly fixed it

I proceeded with the following steps:
Remove every PCI component one by one and reboot each time

Once all PCI components were removed:
Connect every PCI component back until the message shows again

Swap the last 2 PCI card ports

That's it, maybe @Vallevert you didn't have to throw away your PCI card
