SOLVED interrupt storm detected on irq 19

[DMooring]

First I use FreeNas but am not real familiar with FreeBSD or Linux.
I am getting interrupt storm detected on irq 19 scrolling across the console.
FreeNas 9.3.1
MB is SuperMicro X8DTN+
Dual Intel(R) Xeon(R) CPU E5620 @ 2.40GHz
Ram 98G
IBM M1015 controller
8 6ooGig SAS Drives

I have disabled in bios serial ports, floppy controller
I did not disable the usb because I am using usb keyboard.

I have 2 other servers with same MB, controller and Ram only with SATA drives
running FreeNas with no issues.

Code:

I have no clue what you are taking about. Can you provide your freenas version and what is not working correctly.

 

[DMooring]

Fixed,
I disabled the onboard USB ports and installed an USB card.
No more "interrupt storm detected on irq 19 throttling interrupt" messages.

If that is possible on your motherboard, using your ports as USB 2.0 only, and not as USB 3.0 would have likely worked too.

You may want to test that.

 

[DMooring]

The motherboard only had USB 2.0 ports.

Interesting...

Thank you for a speedy answer!
