Description Jens Benecke 2005-09-14 07:05:00 UTC

Hello, 
 
I have a desktop with an nForce2 chipset from ASUS (a7n8x deluxe). When I 
suspend this computer to disk (which works finally in 10.0 - thank you!) and 
then resume, my network is down. ifconfig shows a configured IP, route -n 
shows a route like before, but I cannot connect to any outside machines. 
 
Running "rcnetwork restart" fixes this. This problem does not happen on my 
notebook, which has also been upgraded. Here is my chipset info: 
 
02:01.0 Ethernet controller: 3Com Corporation 3C920B-EMB Integrated Fast 
Ethernet Controller [Tornado] (rev 40) 
00:04.0 Ethernet controller: nVidia Corporation nForce2 Ethernet Controller 
(rev a1) 
 
I tested this with eth0 (nforce2), not the 3Com chip (which I don't need 
here). I also have a notebook with an integrated Intel 855ME chipset and 
Realtek+Intel 2200 wireless (I think) network card, which does not have this 
problem. 
 
Maybe it is related to the power manageability of the nForce2 network card. 
One possible workaround would be to always restart the network after resume, 
which should not hurt in general. 
 
Thanks! :)

For not having to restart the network manually after every suspend, you can add
the network service to the SUSPEND2DISK_RESTART_SERVICES="" variable in
/etc/sysconfig/powersave/sleep

Thanks, I'll try that!

This workaround has to be sufficient for the moment.
Reopen if it does not help.

This worked, until I did something that stopped resume to work altogether. I 
think it was an update of the NVIDIA driver, or it might have been a kernel 
update (since downgrading the NVIDIA driver did not help). 
 
But right now, resume results in a total system freeze with a blank screen, 
even before the kernel boots. It might be some misconfiguration in GRUB.
