At anyrate, I can reproduce, with just the eeprom chip driver. It takes I think between 30 minutes and an hour to reproduce. Also, I have observed the occasional (far less than before going to 2.9.0) panic while unloading drivers as something was invoking the sysctl functionality of the driver. What is rather odd, if I make several connections to the box, and load and unload different drivers in each session (lm93 in one, eeprom in another, ect), I tend to get the out of memory errors much faster. I need to do this again, though just to make sure I hadn't already tainted the system with other tests. Just so you know I can reproduce the memory leaks on both E7501 and E7520 based systems. I did not think it would be system specific but this pretty much tells me its not. I still need to find out if I can get it to cause the out memory errors with other drivers or not. I will send more info when I have it. Cheers...james
