In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
Only say N here if you have a I2O controller from SUN. The SUN
firmware doesn't support LCT notification on changes. If this option
is enabled on such a controller the driver will hang up in a endless
loop. On all other controllers say Y.

If unsure, say Y.
