I'm not sure why our test is triggering cdstrategy() and cdcheckmedia(), which seems to be related to CD? Our test team says the pan= ic happens to FreeBSD 10.3 and the latest HEAD code, meaning this should be a longstanding issue... Anyway, do we have a plan to fix the panic originally reported? --=20 You are receiving this mail because: You are the assignee for the bug.=
