I've seen this one several times before - pagebuf cracks it
when the disk fills:

> dd if=/dev/zero of=x

XFS assertion failed: offset_fsb >= imap[nimaps].br_startoff + 
imap[i].br_blockcount, file: xfs_lrw.c, line: 1681

ADDITIONAL INFORMATION (UPDATE)
From: dxm@engr (BugWorks)
Date: Jul 04 2000 05:31:20PM
==========================

New QA test 015 tests the disk full behaviour.

Doesn't seem to crash & burn anymore, instead gets stuck
"writing" more and more to disk after it fills. dd doesn't
show any signs of returning.
