I can reproduce it with 1G/2G as well. I'm also still seeing the panic on r268286 (11-current), so the version you tested should have failed too. Both of the affected systems are amd64, and both are running on raidz (or raidz-2). I've also been able to reproduce it on a zpool on a single disk. Regards, Kristof
