Subject: BUG: warning at fs/ext3/inode.c:1016/ext3_getblk()

Has anyone seen this before? These three traces occured at different times
today when three new user accounts (and associated quotas) were created. This
machine is an NFS server which uses quotas on an ext3 fs (dir_index is on).
Kernel is 2.6.17.11 on an x86 smp w/64G highmem; 4G ram is installed. The
affected filesystem is on a software raid1 of two hardware raid0 volumes from a
megaraid card.
