This makes the marked pages immune to TLB flushes. Could this be the reason for the P6 Problems ? I belive there is a bit in a control register that will enable/disable this, it's probably in locore.s somewhere. -- Poul-Henning Kamp | phk@FreeBSD.ORG FreeBSD Core-team. http://www.freebsd.org/~phk | phk@login.dknet.dk Private mailbox. whois: [PHK] | phk@ref.tfs.com TRW Financial Systems, Inc.
