I'm looking into the differences in the network switches with the 
chassis vendor.

I don't think this is an interrupt issue.  The switch that changed is 
external to our card.   Its only connection to our card is through a 
PHY, so the network packets it sends would have no interrupt information 
to contained in them.  If it was an interrupt issue,  both of these 
drivers would fail when connecting to any external switch, which is not 
the case.  It would also not explain why the monitor and linux function 
correctly in the same chassis.

Please can you give me a better explanation of your setup. Are your
processor board and Ethernet adapter(s) in the new chassis? Is the e1000
adapter on your processor board or is it on the backplane of the new
chassis? Is the switch part of the chassis or is a separate device? What
is the difference between the old chassis and the new one?

The e1000 driver has been tested on multiple platforms as well as with
multiple different e1000 adapters, so that is why I don't think that this
is a driver related problem.

Thanks, Hugh.

Our card, the XPedite6244, is a mezzanine card based on a MPC7448 with 
an dual Intel 82546 Network controller and MV64460 Gig Ethernet Phys 
that are routed to the backplane.

Our card then plugs into a PTI5071 uTCA chassis.  The PTI50701 has built 
in 16 port Broadcom BCM5396 ethernet switch which is routes 2 of those 
ports to the mezzaine slot of our card.  One for each  ethernet port.

 From the PTI FAE (we have a meeting later today to discuss this in more 
detail):
To answer your high level question the main difference in the 5070 and 
5071 is the fact that the 5071 has a 16 port switch vs. 8 port on 5070. 
This means that dual GigE connections are routed to each AMC bay on 
5071, compared to single GigE connection to AMCs on 5070.

The e1000/i82544 driver is loaded on the XPedite6244.  The driver works 
correctly when communicating with the older version of the external BCM 
8 port ethernet switch.  When we attempt to connect to the 16 port 
BCM5396, the driver causes the card hang.  Both connections are mode 
over the PHY as they are both external to the card running the e1000 driver.

Just to clarify, there is only a single Intel 82546 Network controller, 
but it has two ports.

Since both ports are routed to the same VLAN on the external ethernet 
switch (i.e. the same subnet for each port) does this cause problems for 
the driver even if if_up has not been called?  This causes problems in 
Linux, but only if both ports are brought up at the same time)

Both interfaces being on the same VLAN shouldn't cause a problem for the
driver, but will cause a problem for io-pkt. This still shouldn't cause
the driver to lock up. If you only start one port (io-pkt-v4 -de1000
pci=0) does the driver still hang? Sorry if I have asked this before, but
it has been a while!

This is the output. Note that en0, and en0 are the front panel ethernet interfaces. The back panel interfaces should be 
en2 and en3. This did not hang the card, but it also didn't find the network ports. 

# io-pkt-v4 -de1000 verbose=4,pci=0 
ksh: io-pkt-v4: not found 
# io-net -io-pkt-v4 -de1000 verbose=4,pci=0

# 
# 
# ls /dev/io-net/* 
/dev/io-net/en0 /dev/io-net/ip0 
/dev/io-net/en1 /dev/io-net/ip_en 

I probably won't have much time to work on this until next week, but if I find out anything noteworthy before then, I 
will send it your way.

The io-pkt driver should create wm0/1 interfaces. io-net creates en0/1
interfaces. So are the 2 e1000 interfaces connected to the back panel? If
so, they should be wm0 and wm1 if you run nicinfo.

Hugh,

It looks like the driver cannot handle two network interfaces connected 
to the same subnet.  I was able to use the shelf management software to 
remove one of the ports from the VLAN and both the e1000 and i82544 
drivers worked as expected.  If I add the second network port back to 
the VLAN, the driver causes the card to crash.

I was not able to find a way to have both network ports enabled but load 
the driver for only one of them.

Joe,

Having two interfaces on the same subnet shouldn't cause the driver/card
to crash. Can you start the e1000 driver without any command line
arguments (io-pkt-v4 -de1000) and with both interfaces disconnected. Then
ifconfig both interfaces (ifconfig wm? up) and capture the output from
nicinfo and send it to me. Also the output from 'pidin irq'.

Thanks, Hugh.

Here are the results as you requested, without loading the marvel system controller driver, I would assume the two 
backplane ethernet interfaces will not be discovered.

I forgot that you were running io-net and not io-pkt. The information that
you have sent doesn't help me at all, so please will you run the following:

slay io-net dhcp.client
io-net -de1000
ifconfig en0 up
ifconfig en1 up
nicinfo > file
pidin irq >> file

Send me the output 'file'. If you don't have a file system on your
unit,then you can capture the serial output and send it to me.

Thanks, Hugh.

Here you go. en0 and en1 are front panel ethernet interfaces that do not connect to the chassis. en2 and en3 normally 
represent the back plane network connections to the chassis.

I forgot that you were running io-net and not io-pkt. The information that 
you have sent doesn't help me at all, so please will you run the following: 

slay io-net dhcp.client 
io-net -de1000 
ifconfig en0 up 
ifconfig en1 up 
nicinfo > file 
pidin irq >> file 

Send me the output 'file'. If you don't have a file system on your 
unit,then you can capture the serial output and send it to me. 

Thanks, Hugh.

Looking at the nicinfo output, it appears that the driver is receiving
messages fine. If you leave the driver running for some time and then run
nicinfo, do you see any "Packets dropped on receive" count? Can you run
"dhcp.client -ien0" and get an IP address?

When you say that en0 and en1 are the front panel interfaces, do these
connect to the Intel chip or to another on-board chip? The first driver to
start will allocate en0 and en1 and any subsequent drivers will continue
allocating from en2 up. If you are only running the e1000 driver, then the
2 interfaces will be en0 and en1.

The two front panel ethernet interfaces connect through two external Finisar SFP devices.

I went an re-enabled the second vlan to put us back in the state where the card would fail. Running the same command you
 sent causes the card to crash. I had forgotten to add the 2nd back plane ethernet interface back to the vlan when I 
sent the results before.

From the dump it appears that memory is being corrupted somehow, but
without the hardware, there isn't much more that I can do.
I have looked at the driver initialization and cannot see any place that
the driver could be out of sequence with the hardware.

Hugh.
