From: Mark Linimon <linimon@lonesome.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: Thu, 5 Mar 2009 09:29:11 -0600 ----- Forwarded message from Edward Fisk <7ogcg7g02@sneakemail.com> ----- To: freebsd-bugs@FreeBSD.org From: Edward Fisk <7ogcg7g02@sneakemail.com> Subject: Re: kern/132068: [zfs] page fault when using ZFS over NFS on 7.1-RELEASE/amd64 I tried with the patch kindly provided by Jaakko. The machine would no longer panic, but would instead deadlock every 1-2 hours when in use. I then did a source upgrade to 8-CURRENT (27022008) with a GENERIC kernel, which had the same result: a deadlock every 1 to 2 hours when in use. The machine is now running a GENERIC kernel with the following options added: options INVARIANTS options INVARIANT_SUPPORT options WITNESS options DEBUG_LOCKS options DEBUG_VFS_LOCKS options DIAGNOSTIC Unfortunately, I've yet to be able to get it to deadlock, despite the workload on the machine not having changed. ----- End forwarded message -----
