Subject: ext3 warning from mark_buffer_dirty after aborting journal

Just got this warning when running 2.6.29-rc + yesterdays git on 
sparc64. For some yet unknown reason, scsi disk goes repeatably offline 
during shutdown and this got a warning out of ext3. Is this an expected 
warning or does it need some attention?
