I got heat because a custom Altera part I was driving failed with my 
software. The part worked just fine with the old software (which was 
magnitudes too slow for which it was thrown out).  Clearly my problem. 
After a month of begging, I finally got an afternoon with the hardware 
guy, who took 10 minutes to figure out that the output of an 8 input 
nand gate was ringing into an adjacent line causing false triggers 
elsewhere.  Didn't show up when the part was running at 10% capacity.

And then, and *then*, I got big heat because the i82557 SIO chip would 
start sending 0's. No errors, hardware checksum was ok. This was my 
problem too.  Years later, I found out that shiny new Linux 1.0.3 won't 
support network cards with this chip (3C507) because of this known problem.
Thanks for not mentioning that when you sold us on the buggy chip, intel.
