Description
For testing the issues mentioned in #4588 and #4455, #4454 (synchronous mirror pool on remote devices) i used a single iSCSI COMSTAR provided target on
the same host. On OmniOS r151008j the following procedure crashed the system after blocking for some minutes :
zfs create -V 2G rpool/vol1 stmfadm create-lu /dev/zvol/rdsk/rpool/vol1 stmfadm add-view 600144F000000000000052F8B1390001 svcadm enable -s stmf svcadm enable -s iscsi/target itadm create-target iscsiadm add discovery-address 10.1.0.155:3260 iscsiadm modify discovery --sendtargets enable zpool create test c3t600144F000000000000052F8B1390001d0
On a second try, the command just failed without crashing the system.

The same works on OmniOS-r151006y without any problems. Are there any changes, maybe related to #3740 known causing this problems ?

Although the creation of the zpool worked on OmniOS r151006y, the zfs send I wanted to test on the pool failed with a kernel panic on r151006y also.
zfs create test/testds dd if=/dev/zero of=/test/testds/file1 bs=1M count=50 dd if=/dev/zero of=/test/testds/file2 bs=1M count=50 zfs snapshot test/testds@test zfs send -R test/testds@test | pv > /dev/null
