Initially saw it with zfs send | zfs recv (kernel #71), reproduced outside of X so I could see the panic, installed kernel #72 to be more current (had it compiled but not installed since I was doing lots of I= /O). Didn't happen with zfs send to file, happened on zfs recv from file, grabbed #73 since it looked like it might apply since I have a da* via ISCSI, and can still reproduce the problem. --=20 You are receiving this mail because: You are the assignee for the bug.=
