Public bug reported:
Steps to Reproduce:
1.Boot to BIOS setup menu to change to UEFI mode.
2.Boot form PXE of NIC.
3.Select Ubuntu 14.04.5 for the installing.
4.then, there's an error message appeared, as in the attachment
(/Error_Messages)
When symptom occurs(network configuration failure during installation),
our NIC’s network function still works, i.e., it still can ping to PXE
server.
Logs and trace in the attachment.
/BB_100G: failed case
Install: system installation logs. “syslog” contains more
detailed debug message.
bb.pcapng: network trace.
dmesg.txt: output of system #dmesg
ip_address.txt: output of #ip address show
/Intel_1G: pass case
dmesg.txt
ip_address.txt
intel.zip: zipped network trace.
Quick summary for the test setup:
General PXE server can be used. I referred this page to setup ubuntu
14.04 PXE installation( http://www.tecmint.com/add-ubuntu-to-pxe-network-boot/ )
Add below entry into PXE installation menu “default”
file(/var/lib/tftpboot/pxelinux.cfg/default)
label linux
menu label ^Install Ubuntu 14.04 x64
kernel ubuntu-14.04/ubuntu-installer/amd64/linux
append ks=http://192.168.10.100/linux/ks.cfg vga=normal
initrd=ubuntu-14.04/ubuntu-installer/amd64/initrd.gz ramdisk_size=16432
root=/dev/rd/0 rw netcfg/choose_interface=p4p1 –
The highlighted texts in red need to be changed according to your
server.
Change p4p1 to the interface name shown on your DUT during
installation, in my case p4p1 is used.
Copy all files on Ubuntu 14.04.05 CD to
/var/www/html/Ubuntu1404_x64 for http installation
Put the kickstart configuration “ks.cfg” to /var/www/html/linux
Put the initrd.gz into
/var/lib/tftpboot/ubutu-14.04/Ubuntu-installer/amd64
Please note that the initrd.gz had been injected with our qed.ko and
qede.ko.
The Ubuntu 14.04 netboot I am using is downloaded from
http://archive.ubuntu.com/ubuntu/dists/trusty-updates/main/installer-amd64/current/images/xenial-netboot/
, where amd64 xenial’s 4.4 HWE kernel is used in my setup.
I refereed the below pages to inject our drivers.

We see a bunch of failures in syslogs. could they be causing this ? [We have
seen these failures could cause installation issues on some Ubuntu bugs]
There are no failures specific to driver logs – link etc. also shows connected
for driver interface.
We saw wire shark traces of BB_100G and saw lot of TFTP [Trivial file transfer
protocol ] packets which looks quite same as intel traces.
Is this issue always reproducible or it got passed ever ?

It look like the network configuration failure.
But, We’d tried other vendors’ NICs(Intel and Broadcom), their NICs don’t have
this failure under the same PXE environment...
The major difference is these NICs have had inbox drivers in Ubuntu
netboot(initrd.gz).
