You cannot get the same panic described on kern/121385 as follow: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/121385 How-To-Repeat: # mkdir -p /unionfs/disk1 # mkdir -p /unionfs/disk2 # mount -t unionfs /unionfs/disk1 /unionfs/disk2 # mount -t unionfs /unionfs/disk2 /unionfs/disk1 # touch /unionfs/disk1/foo <freeze or crash> The r178483 (http://svn.freebsd.org/viewvc/base?view=revision&revision=178483) avoids this panic. Try without r178483 and you will get a panic. Some discussions with some developers, we are testing a new cross-mount issue patch, after some more check, I'll open it. thanks :) -- Daichi GOTO, http://people.freebsd.org/~daichiReceived on Thu Dec 04 2008 - 23:55:46 UTC
