Instead, I get a `panic: ufs_ihashget: recursive lock not expected -- pid %d'. Unfirtunately, I didn't save the core dump, so I can't provide a traceback. /tmp is on the root filesystem on my machine. >How-To-Repeat: as above >Fix: >Release-Note: >Audit-Trail: State-Changed-From-To: open->closed State-Changed-By: mpp State-Changed-When: Sat Mar 9 16:20:35 PST 1996 State-Changed-Why: This PR is a duplicate of #1067, which has a better description of the problem, so I opted to keep that one open to track this problem instead. http://www.freebsd.org/cgi/query-pr.cgi?pr=434 State-Changed-From-To: open->closed State-Changed-By: pgollucci State-Changed-When: Thu Sep 16 22:47:54 UTC 2010 State-Changed-Why: reclose http://www.freebsd.org/cgi/query-pr.cgi?pr=434 >Unformatted:
