Comment 48 for bug 12637

I have a 20" iMac and have not yet installed any operating system but OS 10.5, which is an upgrade from the 10.4 it had when new. I thought you folks might be interested to know, this bug is affecting my machine even without Ubuntu, as well as several others I know of personally, and if you google it, a lot of folks around the Mac world. I have tried the "unplug it and wait, then plug it in and boot" method, which didn't work. I then tried the "Zap the P-RAM" method which didn't work either. My tech folks are telling me to try the zap method 5 times in a row and see if that works.
Regardless, just wanted you to know this bug may not be an OS issue at all.
