[Bug 601159] Re: e1000 ethernet port intermitently works

[kc7zzv]

** Description changed:

- I am having trouble with my e1000 integrated ethernet port.  The problem
- is intermittent, happens under Lucid, and not under Windows.  The same
- problem happens on all three identical computers which are Dell Inspiron
- 530s towers.
+ I am having trouble with the e1000 integrated ethernet port on "Inspiron
+ 530s" towers.  The problem is intermittent, happens under Lucid, and not
+ under Windows.  The same problem happens on all three identical
+ computers.
  
  The interface never acquires an ipaddress.  I have tried 2 different
- switches, from two different manfacturers, af both work under Windows
- and not under Lucid.
+ switches, from two different manufacturers, and both times Windows is
+ able to acquire an ipaddress, but Lucid is not.
  
  ethtool says that the card is MDI-X instead of MDI.  Typing "ethtool -s
  eth0 autoneg off" fixes the problem until next reboot.  I do need to
  restart "networking" and "network-manager" to get a ip afterwords
  though.
  
  I put this in /etc/rc.local as a workaround, but I'd really like a better solution:
  ethtool -s eth0 autoneg off
  service network-manager restart && true
  service networking restart && true
  sleep 3
  
  Would looking at anything in a packet sniffer help at all?  Also, Linux
- machines that are NOT Inspiron 530s work just fine.
+ machines that are NOT a "Inspiron 530s" work just fine on my network.
