>Description:
HP BL25p, two mirrored SCSI disks hooked up to ciss (HP SmartArray 6i),
doing NFS serving via bge interfaces on multiple tagged VLANs with CARP.

The filesystem which is exported via nfs is read only, but occasionally
(during the crash it is for sure) is remounted to read write
(mount -o rw -u), doing some svn updates and after that a remount to read
only (mount -o ro -u).  The filesystem in question is mounted asynchronously.

 I can replicate this under FreeBSD 7.0-RELEASE amd64.  I had 9 nfs
 clients using 100MB switched Ethernet running postmark 1.5 into 9
 separate directories....it paniced just when it started to go into
 transaction mode on all of the tests.  When it rebooted, the postmarks
 continued when the nfs share became available and continued to work (I
 am running this bench over the holiday weekend).  I have a vmcore, and
 running kgdb yielded:

 Thanks, looks like it's a different bug that just happens to also 
 involve NFS.

 Thanks, let me know if you need anything.  The exported filesystem is
 ZFS.  Should I open a new ticket?

 Hello, I am checking to see if you need anything else from my server or
 if the problem was discovered.  Sorry, I couldn't see something obvious
 in the NFS code to cause that (it would have to be real obvious for me
 to see it :-) ).  I am just sending this because I will soon need to
 load another OS on the server very soon.  If you would like access to
 the system or discuss how I am replicating the error, please let me know
 soon.
