Hey Jack or anyone on net@,
having updated my sources of HEAD from Dec/Mar to something of last week
I get a lot of:
interrupt storm detected on "irq262:"; throttling interrupt source
Given Intel's driver REDAME I found online says to update the sysctl to this:
hw.intr_storm_threshold=9000
I did that. I then quickly ended up at 25k which still wasn't enough
so I added 2 more zeros to get my console unspammed.
Any idea what the cause for this could be? The few input pps also seem to
keep it quite busy, even if only distributed to a single queue and what netstat
reports is far from ideal.
The pps number it should be able to take should be way higher I feel and I am
sending it a load more pps anyway.
# netstat -I ix1 -w 1
input (ix1) output
packets errs idrops bytes packets errs bytes colls

Is anyone seeing this as well or can reproduce it?
It's a

vendor = 'Intel Corporation'
device = '82598EB 10-Gigabit AF Dual Port Network Connection'
class = network
subclass = ethernet
with only 1 port used currently.
