https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D207464 dustinwenz@ebureau.com changed: What |Removed |Added ---------------------------------------------------------------------------- Severity|Affects Only Me |Affects Many People --- Comment #2 from dustinwenz@ebureau.com --- Turns out this is quite easy to reproduce. In the following example, the sy= stem is booted from a filesystem called "zroot". Running the following three she= ll commands twice in succession consistently causes a panic, even on 10.3-PRERELEASE r295115M: zfs snapshot zroot@panic ls -d /.zfs/snapshot/panic zfs destroy zroot@panic The "ls -d" operation on the .zfs snapshot is required to cause the panic. = It also seems important to do this on a freshly booted system; if many success= ful snapshot/destroy operations are done, the machine stops being susceptible to the panic. The issue is not particularly timing-sensitive. I can still reproduce even = when waiting 5 seconds between operations. --=20 You are receiving this mail because: You are the assignee for the bug.=
