It points to a timing problem most often either the cache has a slow chip in it, or your memory is not really performing at the 60nS speed. It can also be caused by a wrong voltage setting for the CPU chip (there is a five digit code ``SXxxx'' stamped on the top and bottom of your CPU chip, get that to me and I will tell you the correct setting for the CPU voltage). > > Phk just flashed his machine up to that revision and is now seeing soft > > (C-A-D) reboot problems, any such things going on with yours?
