The new Zaptel has the "zttest" program, which will tell you if
interrupts are being locked for too long.  This can cause the Error 500
messages you are seeing.  Causes of interrupts being locked for too long
can be: graphics, frame buffer, IDE DMA.  There might be other things
that cause this error, I don't know.
