So I tried to do a bisect using a reduced config, and I wasn't able to reproduce.  So I went back to 2.6.30-rc1 and started playing with configurations.   I was able to finally get a reproduction, and I found that the af_packet module seems to be responsible.   If I move the modules directory out of the way and reboot, then manually insmod the af_packet module, then suspend, it fails by hanging with the flashing moon LED.  If I reboot and don't load the af_packet module, the suspend works.   Needless to say this falls into the WTF category.   I will do more testing to see what's up...

Attached is my .config.

I'll do that now.

Thanks,
