            Bug ID: 253248
           Summary: Instant panic/restart with mdconfig -t malloc and GELI
           Product: Base System
           Version: 12.2-RELEASE
          Hardware: amd64
                OS: Any

Hi,

my system has 16 GB RAM:

% inxi
CPU: 8-Core Intel Core i7-2820QM (-MCP-) speed/min/max: 2292/800/2301 MHz O=
S:
FreeBSD 12.2-RELEASE-p3 amd64 Up: 3m=20
Mem: 3541.6/16222.2 MB (21.8) Storage: 3.81 TiB (87.9% used) Procs: 93 Shel=
l:
Zsh inxi: 3.1.07

Before the test about 12 GB RAM was free.

After I executed these I got instant panic/restart of the system.

# mdconfig -a -t malloc -s 8G -u 10
# geli onetime -s 4096 /dev/md10
# dd bs=3D1m if=3D/dev/zero of=3D/dev/md10.eli status=3Dprogress

Hope that helps.

Regards.
