Subject: Kernel NFS nfs_update_inode Oops in 2.6.20.11
Date: Sat, 23 Jun 2007 08:33:45 -0700 [thread overview]
Message-ID: <20070623153345.GA22117@ligo.caltech.edu> (raw)
We started receiving frequent kernel (2.6.20.11) Oops messages in
nfs:nfs_update_inode on a pair of Sun X4600M2 machines once we started
mounting an NFS V4 filesystem from a Solaris x86 ZFS server.
Any help in tracking this down would be greatly appreciated.
Thanks.
