Not that Intel is spared from chip problems. This is a problem with the new
G3 PPC chips.


An anonymous source describes a PowerPC 750 floating-point problem as
follows. (We have not yet verified the claim, and we're looking for more
information and testing assistance.)

"The PowerPC 750 floating point problem can be reproduced by feeding
random opcode sequences such that you have repeated floating-point register
stores followed by multiple floating point instructions, resulting in high
activity on the floating point register file. This will in turn produce an
electrical noise sensitivity which will cause erroneous data to be stored
from the floating point register file. This sensitivity to data corruption
is where the Somerset design error comes in, and the fix in silicon is not
expected anytime soon."
