Possibly, but that sure seems like an excessive amount of time just to switch modes, and it would only be from 64 to 32 anyway. I am using 32 bit kernels, home brewed, and just last night got the PAE turned on in 2.6.27-rc8-4, the -4 indicating its built smp etc. But that makes no diff in the wasted time. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
