>Description:
If you have softupdates enabled and write a large file, it's possible
when you shutdown the machine, that syncing gives up before all buffers
are written:

syncing ... 15 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 giving up
>How-To-Repeat:
Write a large file and reboot imediately.
This error may not occur if your harddisk is fast enough
>Fix:
- replace the 20 iterations in syncing by a sysctl variable
- find a better algorithm for syncing
