I've been seeing panics in vm_reserv_alloc_page() for a few days with CURRENT built from sources at 2008-05-09 20:38:25 +0000. The panics seem to be triggered by X11 sessions, but not when I work in the console only. dmesg output and stack traces from the vmcore.{7,8,9,10,11,12} kernel dumps I have around are attached below. Look for 'vmcore.' to find the traces after the dmesg text. [--- dmesg ---] Copyright (c) 1992-2008 The FreeBSD Project.
