>Description:
After setting up ZFS for the first time, and doing some simple stress tests, I was able to quickly crash my system.
I was able to grab this from the core dump in /var/crash:
ad6: FAILURE - device detached
subdisk6: detached
ad6: detached
Fatal trap 12: page fault while in kernel mode
cpuid = 1; apic id = 01

>How-To-Repeat:
1. create a raidz zpool with 3 disks
2. execute:
cat /dev/zero > /zpoolname/file &
cat /dev/urandom > /zpoolname/file2 &
zpool scrub zpoolname
zpool iostat 3
3. let it run for awhile until the system crashes (less than an hour)
