Hi,

there has been a window between April 10 and April 21 where a flaw in
fsck_ffs could cause it to mark filesystems clean when they were
actually not. Luckily only the summary info is affected.

If you have been crashing during this period, I advise you to make
sure fsck_ffs is current, boot to single user mode and then force a
check of all your filesystems.
