Hi, have two intel network card on intel motherboard DZ77(latest bios) with
core i5k (no overcloack) with 32Go XMP1600(kingston)
integer card 82579V and pcie card intel 82572
i use this computer for the LTSP porject server, under ubuntu 12.04.3 amd64
latest kernel 3.8.0-31-generic
those card use e1000e module driver have bug that chrash my ltsp because the
network link is down and my ssh connection betwen client and server is droped
i compile your latest driver e1000e-2.5.4.tar.gz , i try some config explain in
the how to like that (or without setting in modprobe)
# nano -w /etc/modprobe.conf
#<--->
alias eth0 e1000e
alias eth1 e1000e
options e1000e IntMode=2,2 InterruptThrottleRate=3000,3000 RxIntDelay=0
#<--->
and have always this bug after few sec to 5 minutes max
when you use internet (navigate to yahoo and view flash video ) with the client
computer.
LTSP server (this machine with this bug) - one card for Wan and one card (
integrated ) on a switch with 30 fat client disk-less connected. All computer
are 100% Intel (MotherBoard CPU and SSD for server)
the bug come with only one client computer connected to the sever.
this is # dmesg from my server console
# dmesg
