Hi, This is fixed for me in v2.6.19
http://bugs.freedesktop.org/show_bug.cgi?id=5085 points to http://lkml.org/lkml/2006/10/18/68 which is commit 769751f1b920fbd9034a9764443795ce243b547d included in upstream 2.6.19-rc3 It fixes the problem for me. Can you confirm this? commit 769751f1b920fbd9034a9764443795ce243b547d Author: bibo,mao <[EMAIL PROTECTED]> Date: Sat Oct 21 18:37:02 2006 +0200 [PATCH] x86-64: x86_64 add NX mask for PTE entry If function change_page_attr_addr calls revert_page to revert to original pte value, mk_pte_phys does not mask NX bit. If NX bit is set on no NX hardware supported x86_64 machine, there is will be RSVD type page fault and system will crash. This patch adds NX mask bit for PTE entry.
