To quote a message on this list from Claudio Jeker:
I think I mentionened this already a few times but I'll do it again.
"sendto: No buffer space available" means an ENOBUF error was
returned.
On modern systems ENOBUF is almost only generated by the interfaces
and
their queues (e.g. if you enable a too restrictive altq limit).
So if you have altq enabled I would look at the pfctl -sq -vv output.
I do have restrictive altq limit, using upperlimit, since this client
should not be over 22Mbps. At first, I put it at child queue, now I move
them to parent queue (interface). It began to show some noise reduction.
When the queue is full, you get this error.
On the interface SNMP statistic, it's still below 22Mbps. Weird. Maybe
because it's burstyness?
A quick examination of the if_sk code shows that many of the ENOBUFS
return cases also write something to the dmesg/syslog. Does dmesg
show any messages after the 'root on' line?
No, nothing on dmesg.
sk0 shares the same irq as uhci, which is nothing attached to them.
Our
plan
is to disable/change setting for usb config from BIOS. But We really
need to
gather more info on this. Any hints and suggestion will be
appreciated.
PCI, unlike ISA, works just fine with shared interrupts. Do you have
a specific reason to suspect the source of the problem is the sharing
of interrupts?
Actually this suspicion came from an old thread on a milis, which I
gather from google. AFAIK, sk devices don't have interrupt mitigation,
unlike em devices.

I got to admit, I was wrong about these cards capabilities. I'm going to
install INTEL EXPI9402PT, dual ports PCI-express NIC with Intel. 82572GI
Gigabit Controller just to see where the problem is. Anyone knows if this
one support interrupt mitigation?

Insan
