The cd is a bit scratched and old, there are some read timeo= ut debug messages, and the it just reboots. The machine is a Thinkpad T440p. The version of freebsd is 11-current, FreeBSD 11.0-CURRENT #0 r297046 I initially thought it might be drm2/i915kms related, but it panics if those modules are loaded or not. I've attached dmesg, and /var/crash/core.txt.0. /var/crash/info.0 is: Dump header from device: /dev/ada0p3 Architecture: amd64 Architecture Version: 2 Dump Length: 856309760 Blocksize: 512 Dumptime: Thu Mar 24 22:11:03 2016 Hostname: t440p.example.com Magic: FreeBSD Kernel Dump Version String: FreeBSD 11.0-CURRENT #0 r297046: Sat Mar 19 02:16:14 EDT = 2016 root@t440p.example.com:/usr/obj/usr/src/sys/GENERIC Panic String: page fault Dump Parity: 1773259869 Bounds: 0 Dump Status: good --=20 You are receiving this mail because: You are the assignee for the bug.=
