Well, If anyone has ideas, I'm glad to hear about them. I'm running 9.0 MDK 
stock kernel on A20p with 386 mb of RAM. All my hardware seems to work pretty 
reliably, so I don't THINK I have interrupt issues or anything along those 
lines. It just seems that resume from suspend hangs hard 1/3 of the time. 
Anyone else with an A20p out there that has reliable suspend/resume?
