https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D220472 --- Comment #2 from John Kennedy <warlock@phouka.net> --- I've been extremely frustrated trying to get a kernel dump for this panic. Currently: FreeBSD jormungandr.phouka.net 11.1-RC1 FreeBSD 11.1-RC1 #79 r313908+8df37be70f94(releng/11.1): Thu Jul 6 18:20:07 PDT 2017=20=20=20=20 warlock@jormungandr.phouka.net:/usr/obj/usr/src/sys/GENERIC amd64 >From rc.conf: dumpdev=3D"/dev/ada0p1" dumpdir=3D"/var/crash" savecore_enable=3D"YES" # dumpon -l ada0p1 # savecore -Cv unable to open bounds file, using 0 checking for kernel dump on device /dev/ada0p1 mediasize =3D 35433480192 bytes sectorsize =3D 512 bytes magic mismatch on last dump header on /dev/ada0p1 No dump exists I've got a pair of ZFS-mirroed Samsung SSD 960 EVO 250GB drives (/dev/nvd[0= 1]) M.2 drives as zroot. It didn't seem like dumpon liked the encrypted swap partitions on there (even with "late" option), so I threw in a extra drive = and created a unencrypted swap partition on it with enough space for all the memory, just in case. # gpart show /dev/nvd0 =3D> 40 488397088 nvd0 GPT (233G) 40 1024 1 freebsd-boot (512K) 1064 984 - free - (492K) 2048 4194304 2 freebsd-swap (2.0G) 4196352 484200448 3 freebsd-zfs (231G) 488396800 328 - free - (164K) # gpart show /dev/ada0 =3D> 40 937703008 ada0 GPT (447G) 40 4056 - free - (2.0M) 4096 69206016 1 freebsd-swap (33G) 69210112 868492936 - free - (414G) # grep ' memory ' /var/log/dmesg.today=20 real memory =3D 34359738368 (32768 MB) avail memory =3D 33191440384 (31653 MB) Nothing is saved to /var/crash.

Booting to single user after panic and running saveco= re by hand doesn't seem to find anything, either. --=20 You are receiving this mail because: You are the assignee for the bug.=
