The following reply was made to PR kern/132068; it has been noted by GNATS. From: "Edward Fisk" <7ogcg7g02@sneakemail.com> To: bug-followup@freebsd.org Cc: Subject: Re: kern/132068: [zfs] page fault when using ZFS over NFS on 7.1-RELEASE/amd64 Date: 5 Mar 2009 11:46:25 -0000 I've tried the patch kindly supplied by Jaakko, but the machine still deadlocks (no panic though). I then did a source upgrade to 8.0-CURRENT (20090227). The machine would still deadlock every 1-2 hours under the same load. I've now added the following deadlock debugging options: options INVARIANTS options INVARIANT_SUPPORT options WITNESS options DEBUG_LOCKS options DEBUG_VFS_LOCKS options DIAGNOSTIC Unfortunately, the machine has now been running for over 48 hours without a crash, while still being under the same load/usage pattern. -Ed
