Subject: 8169 Intermittent ifup Failure Issue With RTL8102E Chipset in Intel's
 New D945GCLF Atom Board (Not the Initial Modprobe Crash, Another Problem)


(This is a newbie reporting the problem, so take it with a grain of 
salt, to be sure.)

Patch of http://lkml.org/lkml/2008/4/17/298 seems to fix the boot-up 
modprobe crash related to r8169 Intermittent Issue With RTL8102E Chipset 
in Intel's New D945GCLF Atom Board.  However, the r8169 still only seems 
to work with this motherboard / realtek combo a certain percentage of 
the time.  I have found the best luck when unplugging the power supply 
for 5 minutes, and then bring it up cold, thought his was also not 
perfect.  Warm boots, then r8169 driver will load, but not work 
correctly all the time.

I have done most of this testing in 2.6.25-5.  The port led's do come 
on, its just that the driver will (apparently) not pass packets 
correctly, including DHCP packets.

Bounced this off some Intel guys, who had no special ideas at this point 
(see thread 
http://softwarecommunity.intel.com/isn/Community/en-US/forums/thread/30257590.aspx).

Cheers,

- Michael
