>Description:
SMP kernel panics. Filesystems with outstanding/pending writes
are toasted (fsck -y finds hundreds of unconnected inodes and
incorrect inodes).

panic: ffs_blkfree: bad size

>How-To-Repeat:
cvsup sources from 14 Nov 98. Build an SMP kernel. Reboot.
To see the quickly "mount -u -o async /usr". Config kernel
sources, make depend, and fire off "make -j 4".
>Fix:
cvsup with "*default date=98.11.10.00.00.00"
I believe the bug is associated with dg@freebsd.org re-instating
ffs_doreallocblks.
