Once the corruption issues are solved, we can and should put this back. Adrian is working on that.

It's also good for some servers as you need some cores in C-states to get the maximum Turbo Boost on other cores (though that may have been more true for earlier generations of i7 CPUs than more recent generations). -- John Baldwin ___ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"

Yea, it's good for laptops, bad for servers. At least there's some Intel CPUs that this causes corruption with USB. That's being sorted out, but until that's done we need to fail more safe for our primary market.
