I have a GA-M61PM-S2 board running openSuse 10.3 using the onboard ethernet controller with the forcedeth 0.60 driver. The system has been working great for a couple years and this week I decided to try to get suspend-to-ram working due to a huge jump in our electric bill.
Kernel is 22.214.171.124-0.2-default
BIOS is F9c and power management is using S3.
Suspend/resume works fine using pm-suspend except for the network. After resuming, ifconfig shows eth0 is fine, no errors in the s2ram log or syslog, but network is not functional, no traffic in or out. Reloading the forcedeth module doesn’t help.
Suspending multiple times doesn’t change anything, and I found no evidence of the MAC address being backwards like I found in several google results.
I tried both patches I found for the reverse-MAC problem with no change in the problem, and also did my own regression patch for that issue from forcedeth 0.61 from the 2.6.26 kernel source.
I’m not sure if this is purely a driver issue or a problem with the hardware controller or BIOS, but I’m hoping there is a solution other than switching to another ethernet adapter that doesn’t have this issue.
As an aside, it would be nice if 10.3 had a newer version of forcedeth available, it seems there have been a lot of fixes since January 2007. This driver supports a lot of common chipsets.
