[mythtv-users] Why does my dvr randomly drop from the network?

[Rick]

Hi,

I admit I'm in a bit of a panic and I'm fearful that the answer will be 
a bad motherboard.  I'm keeping an open mind!

The problem is my DVR randomly drops from the network within the hour 
after a reboot.  The link beat it still there, it just stops 
communicating.  If I unplug the cable and plug it back in, it comes back 
to life.  If I rmmod r8169 and modprobe r8169 it comes back to life. 
If, however, I shut down eth0 and bring it back up, it doesn't come back 
to life.  I even reset the bios to defaults and started again.

I figured it was something with the OS, so I just reloaded the OS from 
scratch and it happened again.  I'm freakin!

Particulars:
	Distro: Mageia 1 (previously Mandriva 2010.2)
	Kernel now: 2.6.38.8-desktop-5.mga (was 2.6.33.*)
	kernel module: r8169
	Video card: MSI GT218 (newly added after old one bailed)
		Card runs latest Nvidia drivers 275.28
	Motherboard: Gigabyte GA-MA785GM-US2H

Any help is *greatly* appreciated!  Even if it's tell me to use a 
different forum!

Thank you!
R
