The bt shows you are in cpu_idle but what is the full trace. If i had
to bet i would say that this is related to power management issue or
some another interrupt that the OS is waiting for that does not

Alex Hi,
Looks like in 2.4 your apps spent most of the time waiting for data
(select) - and in 2.6 they spend more time doing I/O (writev). I
assume this is network I/O - but it might be disk. If it's network,
check for things that might worsen network I/O: MTU / Csum offloads /
Net card driver +
Try to disable any daemons that might mess with interfaces/routing:
dhclient NetworkManager etc, try see if the problem goes away when
these daemons are down.

I would try to set i to volatile or to an extern to trick the compiler

Something looks rather messed up, since your init function calls a

Could it be some sort of stack corruption?
Not likely. Many times when an init function fails,
it seems that something failed while a module (lpg610) was
initializing, and cleanup was called. At some point during cleanup, an
access to invalid memory was attempted, cusing the oops. what is
lpg610, i searched using lxr got no results. Is this a standard

Every incoming packet goes through input routing. The result of that
routing is either to receive the packet locally, drop, or forward it.
There is a hidden local routing table, that is used to do routing
for incoming packets. It is populated automatically (e.g when u add an
new local interface)
There are many services that does that. Just add the word api to
your google search. An example:
http://smart-ip.net/en/api/
The idea is not to scrape HTML but to query some web service and get a
parsable answer.

I think that the reason for installing PAE kernel as a default is
because the No Execute (aka NX bit) CPU feature is available only when
the CPU is configured to PAE mode. AFAIK the other OS from Redmond
also uses PAE by default (using the ntkrpamp image).
I don't know about performance
Hi Noam,
I recommend you contact Gilad Ben-Yosef (just google the name) - he is
a real pro, both on the technical side and on lecturing about Linux
Kerenl. I've been to some of his lectures, i really think he just
great - and on top he is a nice guy too.
I'm not affiliated to him on any level.
From what i understand - you have 3 network interfaces: one for media,
one for management and loopback.
Why don't you create 2 listeners (media+loopback) from the application
- such that only local connections or connections comming from the
media interface (but not the management) are received?
If you ping another destination during the hang - does it work?
If you ifdown and ifup the interfaces (wan + lan) on the router after
a hang - is it released?
an icmp packet is short so i don't think this is the case but: what is
the MTU on the lan/wan?
Also, use a tool like mtr
is wrong with the outgoing ping request packet.
Did you see any difference between a goog ping and bad ping packets?

My 2 cents: make sure that you have the latest BIOS installed. All pre
OS code relies on BIOS services to discover devices and read/write
data. funky BIOS is not something unheard of.

Say you have 1 box with 2 interfaces, having IP x and y.
When you try to ping or connect to either x or y, the routing table is
being consulted.
The answer of what is the route to x is Local - and it is treated
as loopback.

I still fail to see how this is not an issue with IOAT - if you want to

IOAT - its not a TCP offload engine. Intel's assumption is that the

First off, Zero Copy I/O is enabled in Linux only using the sendfile
