>Description:

	after upgrading my shark to -current a couple of days ago i get repeatable
	panics in he cs driver.  this happens when building software.  it happened
	about 8 times while i built XF4.  this one has a longer stack trace than
	most - most only have 4 frames but still in cs_copy_tx_frame() when losing.
