Hello, I just had a kernel panic on FreeBSD 10.0 RC2 while 'playing' around with iscsi and ZFS. The following steps lead to a kernel panic: - With the iscsi (native) initiator I tried to connect a ietd target. It connects and shows up as /dev/da0 - I try to create a single drive zpool: 'zpool create web004a /dev/da0' - It hangs and dmesg is spammed with: 'WARNING: 10.13.37.3:3260 (iqn.2013-12.nl.searchy.host003:web004a): connection error; reconnecting'. I didn't check any cause of this. - I tried to forcefully remove the iscsi drive with: 'iscsictl -R -t iqn.2013-12.nl.searchy.host003:web004a' - The kernel panic occurs. I can reproduce it with these steps. I don't have checked the target, but I think the iniator should not kernel panic if something goes wrong. Based on the backtrace I would guess it's ZFS related I have stored the crash information here: http://www.frankdebot.nl/freebsd/kernelpanic/20131222/core.txt.1 http://www.frankdebot.nl/freebsd/kernelpanic/20131222/info.1 Regards, Frank de Bot
