Maybe I've just missed it, but has there been any speculation or confirmation about other hardware in combination with CPU upgrades causing the coma problem? I just got a powerlogix 800 mhz upgrade and now my cube won't sleep. Other people don't have this problem and I'm wondering if it has something to do with hardware I have that others may not. In other words, are those of use with geforce 2 mx cards more likely to have problems than those with other graphics cards? Are ADC displays contributing factors? Do sonnet cards wake better? Just wondering. Incidentally, the developer version of Panther doesn't fix it, at least not installed on a firewire drive. Thanks!
