There are: ``` dumpdev=3D"AUTO" ddb_enable=3D"YES" ``` ... lines in /etc/rc.conf I can't enter debugger using sysctl: ``` $ sudo sysctl debug.kdb.enter=3D1 Password: debug.kdb.enter: 0 -> 0 ``` Ctr+Alt+Escape hotkey doesn't work either. I can crash a kernel using: ``` sudo sysctl debug.kdb.panic=3D1 ``` ... command but after reboot there is no dump in /var/crash directory. I tried to reboot without loading i915kms.ko in case it causes these proble= ms. But without this driver screen doesn't turn on after suspend/resume so even= if I enter a debugger I can't read a backtrace. In dmesg -a I see: ``` No suitable dump device was found. /etc/rc: WARNING: failed precmd routine for ddb ``` Full `dmesg -a` after crash and reboot: http://afiskon.ru/s/67/6c0d4868c6_dmesg_a_after_crash.txt I have a single disk partition, no swap: ``` # Device Mountpoint FStype Options Dump Pass# /dev/ada0p2 / ufs rw 1 1 ``` `savecore -v` tells me `savecore: no dumps found`. uname -a: `` FreeBSD e733 11.0-RC2 FreeBSD 11.0-RC2 #0 r304729: Wed Aug 24 06:59:03 UTC = 2016 root@releng2.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC amd64 ``` Any advice? --=20 You are receiving this mail because: You are the assignee for the bug.=
