is it possible to save kernel crashdumps on swap device encrypted with geli= ? 1. i added this lines to the rc.conf: dumpdev=3D"/dev/ad0s1b.eli" dumpdir=3D"/var/crash" 2. mkdir /var/crash;chmod 700 /var/crash 3. then i ran ppp and got panic with a deadlock. 4. cause nothing happennig during a bit of time i pushed reset button. 5. on next boot i got message with impossibillity to save kernel crashdump GEOM_ELI: Device ad0s1b.eli created. GEOM_ELI: Cipher: AES GEOM_ELI: Key length: 256 GEOM_ELI: Crypto: software swapon: adding /dev/ad0s1b.eli as swap device Starting syslogd.
