We recently upgraded one of our NeXT cubes from 16MB of memory to 40MB.   
Everything has seemed to work okay since then, but I just noticed I'm getting  
tons of errors in the /usr/adm/messages file.  This is the error I'm getting:

Jun 10 10:35:14 jgravesnext mach: spurious DMA interrupt
Jun 10 10:36:09 jgravesnext mach: Spurious DMA interrupt - state = 1000000 @  
2000110

It's repeated about once or twice an hour.  I haven't figured out if a single  
program is causing it.  Does anyone have any ideas as to what could be wrong?
