I have a FreeBSD based SAN running on vmWare virtual machine.
There are two disk controllers: built-in Intel Patsburg 6 and LSI logic. Both attached to VM using hardware passthrough.
There are three iSCSI targets on ZFS raidz2 published by using ctld.
Recently I got a problem with one of the disks.
After several reboots I executed 'zpool scrub tank'. At that moment system hanged and kernel panic was generated.
Please find attached auto-generage core.txt report. I can upload vmcore if required.
