>Description:

	Unpacking pkgsrc.tar leads to ffs corruption on both of tested wd raptor WD740GD-75FLA1 disks.
	There is no corruption when softdeps are on or disk write cache is off. There is also no corruption
	when unpacking on seagate ST3200822AS disks connected to the same controller.

	See also http://mail-index.netbsd.org/regional-cs/2004/12/05/0000.html and corresponding thread.	
	
>How-To-Repeat:

	fs not corrupted, boot, unpack pkgsrc.tar, reboot, boot -s, fsck => fsck repairs filesystem corruption
	
	
>Fix:
	

>Unformatted:
