 No improvement.  This is a hardware bug, and the only way to mitigate it
 is to make sure the affected interrupt vectors either are disabled, or
 have extremely short handling times.  Running in polled mode achieves
 that, as does the FreeBSD approach of detecting and suppressing storms.
 
 Should probably be closed "won't fix", as the affected Intel hardware
 gets older, and less likely to run NetBSD.
