This fault/bug has been commented on the STABLE mailing list and is suspected to be related to recent vm changes. >How-To-Repeat: cd /usr/src/sys/i386/conf config GENERIC cd ../../compile/GENERIC make depend make make install reboot [kernel panic ocurrs before any devices are probed] >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
